FEA TURES
•16-bit bus interface
•Multiple V
CC
and GND pins minimize switching noise
•Power-up 3-State
•3-State buffers
•Output capability: +12 mA/–32mA
•Live insertion/extraction permitted
•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
•Same part as 74ABT162244-1
•74ABTH162244 incorporates bus hold data inputs which eliminate
the need for external pull–up resistors to hold unused inputs
•Bus-hold data inputs eliminate the need for external pull-up
resistors to hold unused inputs
DESCRIPTION
The 74ABT162244 high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed.
The 74ABT162244 device is a 16-bit buffer that is ideal for driving
bus lines. The device features four Output Enables (1OE
, 2OE,
3OE
, 4OE), each controlling four of the 3-State outputs.
The 74ABT162244 is designed with 30Ω series resistance in both
the upper and lower output structures. This design reduces line
noise in applications such as memory address drivers, clock drivers
and bus receivers/transmitters.
The 74ABT162244 is the same as the 74ABT16244-1. The part
number has been changed to reflect industry standards.
Two options are available, 74ABT162244 which does not have the
bus hold feature and the 74ABTH162244 which incorporates the bus
hold feature.
