74ABT16240A
16-bit inverting buffer/line driver; 3-state
Rev. 7 — 7 July 2021
Product data sheet
1. General description
The 74ABT16240A is a 16-bit inverting buffer/line driver with 3-state outputs. The device can be
used as four 4-bit buffers, two 8-bit buffers or one 16-bit buffer. The device features four output
enables (1OE, 2OE, 3OE and 4OE), each controlling four of the 3-state outputs. A HIGH on nOE
causes the outputs to assume a high-impedance OFF-state. This device is fully specified for
partial power down applications using IOFF. The IOFF circuitry disables the output, preventing the
potentially damaging backflow current through the device when it is powered down.
2. Features and benefits
Supply voltage range from 4.5 V to 5.5 V
BiCMOS high speed and output drive
Direct interface with TTL levels
Power-up 3-state
IOFF circuitry provides partial Power-down mode operation
Latch-up protection exceeds 500 mA per JESD78B class II level A
16-bit bus interface
Multiple VCC and GND pins minimize switching noise
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
ESD protection:
HBM JESD-A114E exceeds 2000 V
CDM JESD22-C101-C exceeds 1000 V
