Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at
www.onsemi.com.

email any questions regarding the system integration to

MM74HC14 — Hex Inverting Schmitt Trigger
February 2008
MM74HC14
Hex Inverting Schmitt Trigger
Features
■
Typical propagation delay: 13ns
■
Wide power supply range: 2V–6V
■
Low quiescent current: 20µA maximum (74HC Series)
■
Low input current: 1µA maximum
■
Fanout of 10 LS-TTL loads
■
Typical hysteresis voltage: 0.9V at V
CC
=
4.5V
General Description
The MM74HC14 utilizes advanced silicon-gate CMOS
technology to achieve the low power dissipation and
high noise immunity of standard CMOS, as well as the
capability to drive 10 LS-TTL loads.
The 74HC logic family is functionally and pinout compat-
ible with the standard 74LS logic family. All inputs are
protected from damage due to static discharge by inter-
nal diode clamps to V
CC
and ground.
