FEATURES
DESCRIPTION
■ 1500ps max. clock to bus (data transmit)
■ 1000ps max. clock to Q (data receive)
■ Extended 100E VEE range of –4.2V to –5.5V
■ 25Ω cutoff bus outputs
The SY10/100E337 are 3-bit registered bus transceivers
with scan designed for use in new, high- performance ECL
systems. The bus outputs (BUS0–BUS2) are designed to
drive a 25Ω bus; the receive outputs (Q0–Q2) are designed
for 50Ω. The bus outputs feature a normal logic HIGH level
(VOH) and a cutoff LOW level of –2.0V and the output
emitter-follower is “off”, presenting a high impedance to the
bus. The bus outputs also feature edge slow-down
capacitors.
Both drive and receive sides feature the same logic,
including a loopback path to hold data. The LOAD/HOLD
functioniscontrolledbyTransmitEnable(TEN)andReceive
Enable (REN) on the transmit and receive sides,
respectively, with a HIGH selecting LOAD. The
implementation of the E337 Receive Enable differs from
that of the E336.
■ 50Ω receiver outputs
■ Scannable implementation of E336
■ Synchronous and asynchronous bus enables
■ Non-inverting data path
■ Bus outputs feature internal edge slow-down
capacitors
■ Additional package ground pins
■ Fully compatible with industry standard 10KH,
100K ECL levels
■ Internal 75KΩ input pulldown resistors
■ Fully compatible with Motorola MC10E/100E337
■ Available in 28-pin PLCC package
A synchronous bus enable (SBUSEN) is provided for
normal, non-scan operation. The asynchronous bus disable
(ABUSDIS) disables the bus for scan mode.
The SYNCEN input allows either synchronous or
asynchronous re-enabling after disabling with ABUSDIS.
An alternative use is asynchronous-only operation with
ABUSDIS, in which case SYNCEN is tied LOW. SYNCEN
is implemented as an overriding SET control to the enable
flip-flop.
Scan mode is selected by a logic HIGH at the SCAN
input. Scan input data is shifted in through S-IN, and output
data appears at the Q2 output.
All registers are clocked on the rising edge of CLK.
Additional lead-frame grounding is provided through the
ground pins (GND) which should be connected to 0V. The
GND pins are not electrically connected to the chip.
