The TC74VHCT32AFT(EL) is a high-speed CMOS quad 2-input OR gate fabricated with silicon gate CMOS technology. This device achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. It is designed for use in a wide range of digital logic applications, particularly where the OR function is needed.

Applications:

• Logic circuits
• Data selection
• Control systems
• Address decoding
• Signal routing

Features:

• High-speed operation: tpd = 4.8 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 4 μA (max.) at Ta = 25 °C
• TTL input compatible: VIL = 0.8 V (max.); VIH = 2.0 V (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:

• Fast switching speeds for optimal system performance.
• Minimal power consumption ensures energy efficiency.
• Easy interfacing with TTL devices due to input compatibility.
• Capable of driving multiple loads.
• Consistent and predictable timing behavior.
• Reliable performance within a specified voltage range.

The TC74VHCT32AFT(EL) is a quad 2-input OR gate, meaning it contains four independent OR gates. The output (Y) of each gate is high if either input (A or B) is high, or if both inputs are high; otherwise, the output is low. The device is designed for operation within a supply voltage range of 4.5V to 5.5V and is provided in a TSSOP package. Its TTL-compatible inputs allow direct interfacing with TTL devices, making it suitable for mixed logic systems.
