FEATURES

•16-bit bus interface

•Multiple VCC 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

QUICK REFERENCE DATA

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.
