GENERAL DESCRIPTION
74HC/HCT30
The 74HC/HCT30 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL).
They are specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT30 provide the 8-input NAND function.

Note to HCT types
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.
