description

The ’173 and ’LS173A 4-bit registers include
D-type flip-flops featuring totem-pole 3-state
outputs capable of driving highly capacitive
or relatively low-impedance loads. The
high-impedance third state and increased
high-logic-level drive provide these flip-flops with
the capability of being connected directly to and
NC – No internal connection
driving the bus lines in a bus-organized system without need for interface or pull-up components. Up to 128 of
the SN74173 or SN74LS173A outputs can be connected to a common bus and still drive two Series 54/74 or
54LS/74LS TTL normalized loads, respectively. Similarly, up to 49 of the SN54173 or SN54LS173A outputs can
be connected to a common bus and drive one additional Series 54/74 or 54LS/74LS TTL normalized load,
respectively. To minimize the possibility that two outputs will attempt to take a common bus to opposite logic
levels, the output control circuitry is designed so that the average output disable times are shorter than the
average output enable times.
Gated enable inputs are provided on these devices for controlling the entry of data into the flip-flops. When both
data-enable (G1, G2) inputs are low, data at the D inputs are loaded into their respective flip-flops on the next
positive transition of the buffered clock input. Gate output-control (M, N) inputs also are provided. When both
are low, the normal logic states (high or low levels) of the four outputs are available for driving the loads or bus
lines. The outputs are disabled independently from the level of the clock by a high logic level at either
output-control input. The outputs then present a high impedance and neither load nor drive the bus line. Detailed
operation is given in the function table.
The SN54173 and SN54LS173A are characterized for operation over the full military temperature range of
–55°C to 125°C. The SN74173 and SN74LS173A are characterized for operation from 0°C to 70°C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

When either M or N (or both) is (are) high, the output is

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. Voltage values are with respect to network ground terminal.
2. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
length of zero.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in
a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.

Eco Plan
-
The planned eco-friendly classification: Pb-Free (RoHS) or Green (RoHS
&
no Sb/Br)
-
please check
http://www.ti.com/productcontent for the latest availability information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements
for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered
at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame
retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material)
(3)
MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder
temperature.
