FEA TURES
•16-bit bus interface
•Multiple V
CC
and GND pins minimize switching noise
•Power-up 3-State
•3-State buffers
•Output capability: +64 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
•74ABTH16244A 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 74ABT16244A high-performance BiCMOS device combines
low static and dynamic power dissipation with high speed and high
output drive.
The 74ABT16244A 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.
Two options are available, 74ABT16244A which does not have the
bus hold feature and 74ABTH16244A which incorporates the bus
hold feature.
