Product specification

74ABT16244A

74ABTH16244A

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

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.
