Additional Details

The TC74LCX86FK generally operates within a supply voltage range of 2.0V to 3.6V. The propagation delay typically falls within a few nanoseconds, depending on the operating voltage and load conditions. The device is commonly available in surface-mount packages such as SSOP or TSSOP. The operating temperature range usually spans from -40°C to +85°C. The input and output pins are designed to interface seamlessly with other logic families, enhancing its versatility in system design. Each of the four XOR gates operates independently, providing flexibility in circuit configuration. XOR gates output a logic high only when one of the inputs is high, and the other is low; otherwise, the output is low.
