74LVT16240A
Rev. 4 — 1 October 2018
3.3 V 16-bit inverting buffer/driver; 3-state
Product data sheet
1. General description
The 74LVT16240A is a high-performance BiCMOS product designed for V
CC
operation at 3.3 V.
This device 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.

The input and output negative voltage ratings may be exceeded if the input and output clamp 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.
