Functional Description
As shown in the block diagram the 9403A consists of three
sections:
the F flip-flop and resetting the other flip-flops. The Q out-
3
put of the last flip-flop (FC) is brought out as the ‘Input Reg-
ister Full’ output (IRF). After initialization this output is HIGH.
1. An Input Register with parallel and serial data inputs as
well as control inputs and outputs for input handshaking
and expansion.
Parallel EntryÐA HIGH on the PL input loads the D –D

inputs into the F –F flip-flops and sets the FC flip-flop. This

forces the IRF output LOW indicating that the input register
is full. During parallel entry, the CPSI input must be LOW. If
parallel expansion is not being implemented, IES must be
LOW to establish row mastership (see Expansion section).
2. A 4-bit wide, 14-word deep fall-through stack with self-
contained control logic.
3. An Output Register with parallel and serial data outputs
as well as control inputs and outputs for output hand-
shaking and expansion.

After the fourth clock transition, the four data bits are locat-

The Input Register can receive data in either bit-serial or in
4-bit parallel form. It stores this data until it is sent to the fall-
through stack and generates the necessary status and con-
trol signals.

through’ action. If the top location of the stack is empty,
data is loaded into the stack and the input register is re-ini-
tialized. Note that this initialization is postponed until PL is
LOW again. Thus, automatic FIFO action is achieved by
connecting the IRF output to the TTS input.
An RS Flip-Flop (the Request Initialization Flip-Flop shown
in Figure 10 ) in the control section records the fact that
data has been transferred to the stack. This prevents multi-
ple entry of the same word into the stack despite the fact
the IRF and TTS may still be LOW. The Request Initializa-
tion Flip-Flop is not cleared until PL goes LOW. Once in the
stack, data falls through the stack automatically, pausing
only when it is necessary to wait for an empty next location.
In the 9403A as in most modern FIFO designs, the MR input
only initializes the stack control section and does not clear
the data.
OUTPUT REGISTER (DATA EXTRACTION)
The Output Register receives 4-bit data words from the bot-
tom stack location, stores it and outputs data on a TRI-
STATE 4-bit parallel data bus or on a TRI-STATE serial data
bus. The output section generates and receives the neces-
sary status and control signals. Figure 3 is a conceptual
logic diagram of the output section.

FIGURE 3. Conceptual Output Section
Parallel Data ExtractionÐWhen the FIFO is empty after a
LOW pulse is applied to MR, the Output Register Empty
(ORE) output is LOW. After data has been entered into the
FIFO and has fallen through to the bottom stack location, it
is transferred into the Output Register provided the ‘Trans-
fer Out Parallel’ (TOP) input is HIGH. As a result of the data
transfer ORE goes HIGH, indicating valid data on the data
outputs (provided the TRI-STATE buffer is enabled). TOP
can now be used to clock out the next word. When TOP
goes LOW, ORE will go LOW indicating that the output data
has been extracted, but the data itself remains on the output
bus until the next HIGH level at TOP permits the transfer of
the next word (if available) into the Output Register. During
parallel data extraction CPSO should be LOW. TOS should
be grounded for single slice operation or connected to the
appropriate ORE for expanded operation (see Expansion
section).
control circuitry prevents the same data from being trans-
ferred twice. If TOP goes HIGH and returns to LOW before
data is available from the stack, ORE remains LOW indicat-
ing that there is no valid data at the outputs.
Serial Data ExtractionÐWhen the FIFO is empty after a
LOW pulse is applied to MR, the Output Register Empty
(ORE) output is LOW. After data has been entered into the
FIFO and has fallen through to the bottom stack location, it
is transferred into the Output Register provided TOS is LOW
and TOP is HIGH. As a result of the data transfer ORE goes
HIGH indicating valid data in the register. The TRI-STATE
Serial Data Output, Q , is automatically enabled and puts
S
the first data bit on the output bus. Data is serially shifted
out on the HIGH-to-LOW transition of CPSO. To prevent
false shifting, CPSO should be LOW when the new word is
being loaded into the Output Register. The fourth transition
empties the shift register, forces ORE output LOW and dis-
TOP is not edge triggered. Therefore, if TOP goes HIGH
before data is available from the stack, but data does be-
come available before TOP goes LOW again, that data will
be transferred into the Output Register. However, internal
ables the serial output, Q (refer to Figure 3 ). For serial
S
operation the ORE output may be tied to the TOS input,
requesting a new word from the stack as soon as the previ-
ous one has been shifted out.

EXPANSION
a
(15n 1)-words by 4-bits can be constructed, where n is the
number of devices. Note that expansion does not sacrifice
any of the 9403A’s flexibility for serial/parallel input and out-
put.
Vertical ExpansionÐThe 9403A may be vertically expand-
ed to store more words without external parts. The intercon-
nection is necessary to form a 46-word by 4-bit FIFO are
shown in Figure 4. Using the same technique, and FIFO of

Functional Description (Continued)
Horizontal ExpansionÐThe 9403A can also be horizontal-
ly expanded to store long words (in multiples of four bits)
without external logic. The interconnections necessary to
form a 16-word by 12-bit FIFO are shown in Figure 5. Using
the same technique, any FIFO of 16 words by 4n bits can be
constructed, where n is the number of devices. The IRF
output of the right most device (most significant device) is
connected to the TTS inputs of all devices. Similarly, the
ORE output of the most significant device is connected to
the TOS inputs of all devices. As in the vertical expansion
scheme, horizontal expansion does not sacrifice any of the
9403A’s flexibility for serial/parallel input and output.
master in their row. No slave in a given row will initialize its
Input Register until it has received LOW on its IES input
from a row master or a slave of higher priority.
In a similar fashion, the ORE outputs of slaves will not go
HIGH until their OES inputs have gone HIGH. This interlock-
ing scheme ensures that new input data may be accepted
by the array when the IRF output of the final slave in that
row goes HIGH and that output data for the array may be
extracted when the ORE of the final slave in the output row
goes HIGH.
The row master is established by connecting its IES input to
ground while a slave receives its IES input from the IRF
output of the next higher priority device. When an array of
9403A FIFOs is initialized with a LOW on the MR inputs of
all devices, the IRF outputs of all devices will be HIGH.
Thus, only the row master receives a LOW on the IES input
during initialization. Figure 10 is a conceptual logic diagram
of the internal circuitry which determines master/slave oper-
ation. Whenever MR and IES are LOW, the Master Latch is
set. Whenever TTS goes LOW the Request Initialization
Flip-Flop will be set. If the Master Latch is HIGH, the Input
Register will be immediately initialized and the Request Ini-
tialization Flip-Flop reset. If the Master Latch is reset, the
Input Register is not initialized until IES goes LOW. In array
operation, activating the TTS initiates a ripple input register
initialization from the row master to the last slave.
Horizontal and Vertical ExpansionÐThe 9403A can be
expanded in both the horizontal and vertical directions with-
out any external parts and without sacrificing any of its FI-
FO’s flexibility for serial/parallel input and output. The inter-
connections necessary to form a 31-word by 16-bit FIFO are
shown in Figure 6. Using the same technique, any FIFO of
a
(15m 1)-words by (4n)-bits can be constructed, where m is
the number of devices in a column and n is the number of
devices in a row. Figures 7 and 8 show the timing diagrams
for serial data entry and extraction for the 31-word by 16-bit
FIFO shown in Figure 6. The final position of data after seri-
al insertion of 496 bits into the FIFO array of Figure 6 is
shown in Figure 9.
Interlocking CircuitryÐMost conventional FIFO designs
provide status signals analogous to IRF and ORE. However,
when these devices are operated in arrays, variations in unit
to unit operating speed require external gating to assure all
devices have completed an operation. The 9403A incorpo-
rates simple but effective ‘master/slave’ interlocking circuit-
ry to eliminate the need for external gating.
A similar operation takes place for the output register. Either
a TOS or TOP input initiates a load-from-stack operation
and sets the ORE Request Flip-Flop. If the Master Latch is
set, the last Output Register Flip-Flop is set and ORE goes
HIGH. If the Master Latch is reset, the ORE output will be
LOW until an OES input is received.
In the 9403A array of Figure 6 devices 1 and 5 are defined
as ‘row masters’ and the other devices are slaves to the
