74HC30 datasheet



The 74HC30 and 74HCT30 each contain an 8-input NAND gate in one package. They provide the system designer with the direct implementation of the positive logic 8-input NAND function.

A CMOS (Complementary Metal-Oxide-Semiconductor) logic 8-input NAND gate is a digital logic gate that performs the logical NAND operation on eight input signals. The output of the gate is the logical negation (NOT) of the logical AND operation performed on the eight input signals.

Logic gates utilize silicon gate CMOS technology to achieve operating speeds similar to LSTTL gates with the low power consumption of standard CMOS integrated circuits.

All devices have the ability to drive 10 LSTTL loads. The HCT logic family is functionally pin compatible with the standard LS logic family.
