The TC74HCT86AF is a high-speed CMOS quad 2-input Exclusive-OR gate fabricated with silicon gate C2MOS technology. It achieves high-speed operation similar to equivalent Schottky TTL while maintaining the low power dissipation of CMOS. This device is well-suited for a wide range of applications requiring Exclusive-OR logic functions.

Applications

• Parity generators/checkers
• Adders/subtractors
• Code converters
• Logic comparators
• Data encryption

Features

• High-speed operation: tpd = 13 ns (typ.) at VCC = 5 V
• 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 = 4.5 V to 5.5 V

Benefits

• Improved system performance due to high-speed operation.
• Reduced power consumption leading to energy efficiency.
• Enhanced noise immunity, ensuring reliable operation in noisy environments.
• Direct compatibility with LSTTL devices, simplifying system integration.
• Stable and predictable performance due to balanced propagation delays.

Additional Details

The TC74HCT86AF is supplied in a 14-pin SOIC (Small Outline Integrated Circuit) package. It is pin-compatible with standard TTL logic gates. The device operates over a temperature range of -40°C to +85°C. The inputs are protected against static discharge. The absolute maximum ratings should not be exceeded to prevent damage to the device.
