FEATURES
Independent registers for A and B buses
Multiple V
CC
and GND pins minimize switching noise
Power-up 3-State
74ABTH16652 incorporates bus-hold data inputs which eliminate
the need for external pull-up resistors to hold unused inputs
Power-up reset
Live insertion/extraction permitted
Multiplexed real-time and stored data
Output capability: +64mA/–32mA
Latch-up protection exceeds 500mA per JEDEC Std 17
ESD protection exceeds 2000V per MIL STD 883 Method 3015
and 200V per Machine Model
DESCRIPTION
The 74ABT16652 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16652 transceiver/register consists of two sets of bus
transceiver circuits with 3-State outputs, D-type flip-flops, and
control circuitry arranged for multiplexed transmission of data
directly from the input bus or the internal registers. Data on the A or
B bus will be clocked into the registers as the appropriate clock pin
goes HIGH. Output Enable (nOEAB, (nOEBA) and Select (nSAB,
nSBA) pins are provided for bus management.
Two options are available, 74ABT16652 which does not have the
bus-hold feature and 74ABTH16652 which incorporates the
bus-hold feature.
