Product Description

74HC04 Hex Inverter Logic Gate IC

High-Speed CMOS Hex Inverter for Digital Logic and Signal Inversion

The 74HC04 is a high-speed CMOS logic IC containing six independent inverting buffers. Each inverter produces a HIGH output when the input is LOW, and a LOW output when the input is HIGH. This basic yet essential logic function is used for signal inversion, level shifting, oscillator circuits, and interface conditioning in digital systems.

Operating voltage range: 2.0V to 6.0V
Propagation delay: 7ns typical at 5V
Output drive capability: ±5.2mA at 6V
Do not exceed 7.0V supply voltage - permanent damage may occur
Unused inputs must be tied to VCC or GND - floating inputs can cause oscillation

Package Includes

  1. 1x 74HC04 Logic IC (Package: DIP14, SOIC14, or TSSOP-14 per variant)
  2. Anti-static packaging for safe delivery
For crystal oscillator circuits, use one inverter with feedback resistor and two capacitors
Use inverter as buffer by cascading two inverters in series
This IC is also available as 74HCT04 for TTL-compatible input levels
Inverter with input tied LOW produces constant HIGH output
Inverter with input tied HIGH produces constant LOW output
Multiple inverters can be used to create ring oscillators for clock generation
For LED driving, use inverter to sink current from LED to ground
Never leave inputs floating use pullup or pull-down resistors
ESD sensitive device - use proper handling procedures
Ensure decoupling capacitor (0.1µF) is placed near VCC pin
