00 — Overview

What the 74HC00 family does

The 74HC00 and 74HCT00 are quad 2-input NAND gates available in SO14, TSSOP14, and DHVQFN14 packages across commercial and industrial temperature ranges. These devices operate with a wide supply voltage from 2.0 to 6.0 V, featuring CMOS low power dissipation and high noise immunity. Input levels differ between the HC and HCT variants, with the latter supporting TTL levels. The gates include clamp diodes to allow current limiting resistors for interfacing inputs to voltages exceeding VCC. They are typically used in digital logic circuits requiring robust noise immunity and latch-up performance exceeding 100 mA per JESD 78 Class II Level B standards.
