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:

AY =

Features

• Wide Supply Voltage Range from 2.0V to 5.5 V

• Outputs Sink or Source 8mA at V

= 4.5V

• CMOS Low Power Consumption

• 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.

• Inputs can be driven by 3.3V or 5.5V allowing for voltage

translation applications.

• ESD Protection Exceeds JESD 22
