74ABT16244A
16-bit buffer/line driver; 3-state
Rev. 8 — 3 November 2011
Product data sheet
1. General description
The 74ABT16244A high-performance Bipolar CMOS (BiCMOS) device combines low
static and dynamic power dissipation with high speed and high output drive.
The 74ABT16244A is a 16-bit buffer that is ideal for driving bus lines. The device features
four output enable inputs (1OE, 2OE, 3OE, 4OE), each controlling four of the 3-state
outputs.
2. Features and benefits
16-bit bus interface
Multiple VCC and GND pins minimize switching noise
Power-up 3-state
3-state buffers
Output capability: +64 mA and 32 mA
Live insertion and extraction permitted
Latch-up performance: JESD 78 Class II
ESD protection:
HBM JESD-A114E exceeds 2000 V
CDM JESD 22-C101-C exceeds 1000 V
