74ABT16240A
16-bit inverting buffer/line driver; 3-state
Rev. 6 — 3 November 2011
Product data sheet
1. General description
The 74ABT16240A high-performance BiCMOS device combines low static and dynamic
power dissipation with high speed and high output drive.
The 74ABT16240A is an inverting 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 V
CC
and GND pins minimize switching noise
Power-up 3-state
3-state buffers
TTL input and output switching levels
Input and output interface capability to systems at 5 V supply
Output capability: +64 mA and
32
mA
Live insertion and extraction permitted
Latch-up protection exceeds 500 mA per JESD78 class II level A
ESD protection:
HBM JESD-A114E exceeds 2000 V
CDM JESD22-C101-C exceeds 1000 V

The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction
temperatures which are detrimental to reliability.
