Product Description

74HC86 Quad 2-Input XOR (Exclusive OR) Logic Gate IC

High-Speed CMOS XOR Gate for Digital Logic Applications

The 74HC86 is a highspeed CMOS logic IC featuring four independent 2input XOR (Exclusive OR) gates. The XOR gate produces a HIGH output when the two inputs are at different logic levels, and a LOW output when they are the same. This unique property makes the 74HC86 essential for digital comparators, parity generators, adder circuits, and pulse edge detectors.

Operating voltage range: 2.0V to 6.0V
Propagation delay: 11ns 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 74HC86 XOR Logic IC (Package: DIP14, SOIC14, or TSSOP-14 per variant)
  2. Anti-static packaging for safe delivery
For parity generation, feed all data bits to separate XOR gates and chain outputs
For edge detection, connect one input of XOR to a delayed version of the signal
This IC is also available as 74HCT86 for TTL-compatible input levels
XOR gate with one input tied HIGH acts as an inverting buffer
XOR gate with one input tied LOW acts as a non-inverting buffer
Use in data scrambling and CRC calculation circuits
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
