74AHC14
HEX INVERTERS WITH SCHMITT TRIGGER INPUTS
Description
Pin Assignments
(Top View )
The 74AHC14 provides provides six independent Schmitt trigger input
inverters with standard push-pull outputs. The device is designed for
operation with a power supply range of 2.0V to 5.5V. The inputs are
tolerant to 5.5V allowing this device to be used in a mixed voltage
environment.

Schmitt Trigger Action at All Inputs
Typical hysteresis of 1V allows for transformation of slow
changing input signals to sharply defined, fast transition output
signals.
Applications
•
