FEATURES
• Output capability: standard
• I
CC
category: SSI
GENERAL DESCRIPTION
The 74HC/HCT4075 are high-speed Si-gate CMOS
devices and are pin compatible with the “4075” of the
“4000B” series. They are specified in compliance with
JEDEC standard no. 7A.
The 74HC/HCT4075 provide the 3-input OR function.
