74AHCT17A
Rev. 1 — 18 May 2017
Hex buffer Schmitt trigger
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.

If the input current ratings are observed, the minimum input voltage ratings may be exceeded.
If the output current ratings are observed, the output voltage ratings may be exceeded.
This value is limited to 7 V maximum.
For TSSOP14 package: above 75 °C, the value of P
tot
derates linearly at 7 mW/K.
