Product Description

74HC08 Quad 2-Input AND Logic Gate IC

High-Speed CMOS AND Gate for Digital Logic and Control Applications

The 74HC08 is a highspeed CMOS logic IC featuring four independent 2input AND gates. The AND gate produces a HIGH output only when ALL inputs are HIGH, and a LOW output when any input is LOW. This fundamental logic function is essential for enable/disable circuits, signal gating, address decoding, and permission-based control systems.

Operating voltage range: 2.0V to 6.0V
Propagation delay: 8ns 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 excessive power consumption and oscillation

Package Includes

  1. 1x 74HC08 Logic IC (Package: DIP14, SOIC14, or TSSOP-14 per variant)
  2. Anti-static packaging for safe delivery
Use AND gate as a signal pass-through by tying one input HIGH
For active-low enable, use AND gate combined with an inverter
This IC is also available as 74HCT08 for TTL-compatible input levels
AND gate with one input tied LOW produces constant LOW output - useful for disabling signal paths
AND gate with one input tied HIGH acts as a noninverting buffer (passthrough)
Multiple AND gates can be cascaded to create wide-input AND functions up to 8 bits
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
