FEA TURES
•Power-up 3-State
•Multiple V
CC
and GND pins minimize switching noise
•Provides ideal interface and increases fan-out of MOS
Microprocessors
•3-State buffers sink 64mA and source 32mA
•74ABTH16541 incorporates bus-hold data inputs which eliminate
the need for external pull-up resistors to hold unused inputs
•Latch-up protection exceeds 500mA per Jedec Std 17
•ESD protection exceeds 2000 V per MIL STD 883 Method 3015
and 200 V per Machine Model
•Two 8-bit bus interfaces
•Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
DESCRIPTION
The 74ABT16541 high-performance BiCMOS device combines low
static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16541 has two octal buffers that are ideal for driving bus
lines. The outputs are all capable of sinking 64mA and sourcing
32mA.
Two options are available, 74ABT16541 which does not have the
bus-hold feature and 74ABTH16541 which incorporates the
bus-hold feature.
