GENERAL DESCRIPTION
74HC/HCT4075
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.

Note to HCT types
74HC/HCT4075
The value of additional quiescent supply current (∆I
CC
) for a unit load of 1 is given in the family specifications.
To determine
∆I
CC
per input, multiply this value by the unit load coefficient shown in the table below.
