HEX INVERTERS WITH SCHMITT TRIGGER INPUTS
Description
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.
The gates perform the Boolean function:

Features
•
Wide Supply Voltage Range from 2.0V to 5.5 V
•
Outputs Sink or Source 8mA at V
CC
= 4.5V
