Typical Applications
SN74HCS86PWR is suitable for 6 applications: Signal Conditioning, Parity Generation and Checking, Comparator Circuits, Oscillator Circuits, Data Communication, Industrial Control.
Signal Conditioning
The SN74HCS86PWR's Schmitt-trigger inputs provide hysteresis, making it ideal for cleaning up noisy signals from switches, sensors, and encoders. The hysteresis prevents multiple transitions when the input signal is slow or noisy, ensuring a clean digital output. This is critical in industrial environments where electrical noise is prevalent. The device operates from 2V to 6V, allowing it to interface with both 3.3V and 5V logic systems. Its TSSOP-14 package is compact, saving PCB space. For best results, place the device close to the signal source and use proper decoupling capacitors on the power supply.

Parity Generation and Checking
The SN74HCS86PWR is commonly used in parity generation and checking circuits for data communication. XOR gates are fundamental to parity logic, producing a high output when the number of high inputs is odd. The device's four independent gates allow implementation of 8-bit parity generators or checkers. Its wide supply voltage range (2V to 6V) makes it compatible with various logic families. The Schmitt-trigger inputs ensure reliable operation even with degraded signal integrity over long transmission lines. For high-speed data links, ensure the propagation delay meets your timing budget.

Comparator Circuits
The SN74HCS86PWR can be used to build comparator circuits that detect differences between two digital signals. By connecting the two inputs to the signals being compared, the XOR output goes high when they differ. This is useful in applications such as phase detection, frequency comparison, and error detection. The Schmitt-trigger inputs provide noise immunity, ensuring accurate comparison even in noisy environments. The device's low power consumption makes it suitable for battery-powered applications. For best performance, ensure input signals are within the supply voltage range and have fast rise/fall times.

Design Notes
The SN74HCS86PWR operates from 2V to 6V. Ensure the supply voltage is within this range and is stable. Use a 0.1uF decoupling capacitor close to the VCC pin to filter high-frequency noise. For systems with multiple logic devices, consider a bulk capacitor on the power rail.
Place the SN74HCS86PWR close to the signal source to minimize trace length and reduce noise pickup. Use a solid ground plane to provide a low-impedance return path. Keep input and output traces separated to avoid crosstalk. For best signal integrity, use controlled impedance traces if the signals are high-speed.
Do not leave unused inputs floating, as this can cause undefined logic levels and increase power consumption. Tie unused inputs to VCC or GND. Also, ensure input signals do not exceed the supply voltage range to avoid latch-up. The device can drive loads up to 50 pF; larger loads may require a buffer.
