00 — Overview

What the 74HC04 family does

The 74HC04 and 74HCT04 are hex inverters available in commercial, industrial, and military temperature grades. These devices operate across a wide supply voltage range from 2.0 V to 6.0 V, featuring CMOS low power dissipation and high noise immunity. Input levels adapt to CMOS or TTL standards depending on the specific type. The parts support multiple package options including SO14, TSSOP14, and various leadless quad flat packages. They are specified for temperatures from -40 °C to +85 °C or -40 °C to +125 °C. The inverters include clamp diodes on inputs to allow interfacing with voltages exceeding VCC. They comply with JEDEC standards for latch-up performance and ESD protection. These components are typically used in digital logic circuits requiring signal inversion.
