74AHCT17A
Hex buffer Schmitt trigger
Rev. 1 — 18 May 2017 Product data sheet
1 General description
The 74AHCT17A is a hex buffer with Schmitt-trigger inputs, capable of transforming
slowly changing input signals into sharply defined, jitter-free output signals.
Designed to operate over a V
CC
range from 4.5 V to 5.5 V, the inputs are TTL
compatible. This range allows the device to be used to translate from 3.3 V to 5 V.
This device is fully specified for partial Power-down applications using I
OFF
. The I
OFF
circuitry disables the output, preventing the damaging backflow current through the
device when it is powered down.
