The TC74HC86AFN(ELF is a high-speed CMOS quad 2-input exclusive-OR gate manufactured by Toshiba Semiconductor and Storage. It is fabricated with silicon gate CMOS technology, achieving high-speed operation similar to equivalent Schottky TTL while maintaining the low power dissipation characteristic of CMOS. The device consists of four independent 2-input XOR gates.

Applications

• Parity generators and checkers
• Adders and subtractors
• Data encryption
• Code converters
• Logic comparators
• General digital logic

Features

• High-speed operation: tpd = 11 ns (typ.) at VCC = 5V
• Low power dissipation: ICC = 4 μA (max.) at Ta = 25°C
• High noise immunity: VNIH = VNIL = 28 % VCC (min.)
• Output drive capability: 10 LSTTL loads
• Symmetrical output impedance: |IOH| = IOL = 4 mA (min.)
• Balanced propagation delays: tPLH ≈ tPHL
• Wide operating voltage range: VCC = 2 V to 6 V
• Pin and function compatible with 74HC86

Benefits

• High-speed performance allows use in time-sensitive applications.
• Low power consumption contributes to energy efficiency.
• High noise immunity ensures stable operation in noisy environments.
• Large output drive capability facilitates interfacing with other logic devices.
• Wide operating voltage range adds design flexibility.
• Simplified design due to pin compatibility with industry-standard 74HC86.

Additional Details

Each XOR gate in the TC74HC86AFN(ELF) implements the Boolean function Y = A ⊕ B, where Y is the output and A and B are the inputs. The output is HIGH only when one, but not both, of the inputs are HIGH. This characteristic makes it suitable for parity checking and similar applications. The (ELF suffix likely refers to the specific packaging and reel options.

The operating temperature range is typically -40°C to +85°C. The package is a SO14.
