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.

74AC14, 74ACT14
Hex Inverter with Schmitt Trigger Input
Features
■
I
CC
reduced by 50%
■
Outputs source/sink 24mA
■
74ACT14 has TTL-compatible inputs
General Description
The 74AC14 and 74ACT14 contain six inverter gates
each with a Schmitt trigger input. They are capable of
transforming slowly changing input signals into sharply
defined, jitter-free output signals. In addition, they have a
greater noise margin than conventional inverters.
The 74AC14 and 74ACT14 have hysteresis between the
positive-going and negative-going input thresholds (typi-
cally 1.0V) which is determined internally by transistor
ratios and is essentially insensitive to temperature and
supply voltage variations.
