CD74HCT86M

CD74HCT86M Description

The CD74HCT86M from Texas Instruments is a high-speed CMOS logic XOR (Exclusive OR) gate integrated circuit housed in a 14-pin SOIC package. Designed for surface-mount applications, it features four independent 2-input XOR gates, making it ideal for digital logic operations requiring parity generation, error detection, or signal comparison. Operating within a 4.5V to 5.5V supply range, it ensures compatibility with TTL logic levels (input high: 2V, input low: 0.8V) while delivering low power consumption (2 µA quiescent current). With a maximum propagation delay of 32ns at 4.5V and 50pF load, it balances speed and efficiency for medium-speed digital systems.

CD74HCT86M Features

• Logic Type: 4-channel XOR gate with 2 inputs per channel, enabling flexible logic design.
• High-Speed Performance: 32ns propagation delay ensures reliable timing in critical applications.
• Wide Voltage Range: 4.5V–5.5V operation with TTL-compatible inputs for seamless integration.
• Low Power: 2 µA quiescent current minimizes energy waste in battery-powered systems.
• Robust Output Drive: 4mA output current (high/low) supports moderate fan-out requirements.
• Reliability: ROHS3 compliant, REACH unaffected, and MSL 1 (unlimited) for environmental and handling resilience.
• Packaging: Supplied in tube packaging for automated assembly efficiency.

CD74HCT86M Applications

• Digital Signal Processing: Parity checkers, error detection circuits, and arithmetic logic units (ALUs).
• Communication Systems: Signal encoding/decoding and phase comparators in data transmission.
• Control Systems: State machine design and logic-level translation in embedded systems.
• Test Equipment: Pulse generation and frequency monitoring in diagnostic tools.
• Consumer Electronics: Keypad scanning and interface logic in smart devices.
