FEATURES
Two 8-bit registered transceivers
Live insertion/extraction permitted
Power-up 3-State
74ABTH16952 incorporates bus-hold data inputs which eliminate
the need for external pull-up resistors to hold unused inputs
Power-up reset
Multiple V
CC
and GND pins minimize switching noise
Independent registers for A and B buses
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
Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
DESCRIPTION
The 74ABT16952 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16952 is a dual octal registered transceiver. Two 8-bit
registers store data flowing in both directions between two
bidirectional buses. Data applied to the inputs is entered and stored
on the rising edge of the Clock (nCPXX) provided that the Clock
Enable (nCEXX) is Low. The data is then present at the 3-State
output buffers, but is only accessible when the Output Enable
(nOEXX) is Low. Data flow from A inputs to B outputs is the same as
for B inputs to A outputs.
Two options are available, 74ABT16952 which does not have the
bus-hold feature and 74ABTH16952 which incorporates the
bus-hold feature.
