The TC74VHCT08FS is a high-speed CMOS quad 2-input AND gate fabricated with silicon gate CMOS technology. Designed for high-performance applications, it combines the speed of bipolar logic with the benefits of CMOS low power consumption. This device is commonly used in digital logic circuits for performing AND operations.
Applications:
- Logic gates
- Digital comparators
- Address decoding
- Data selection
- Control circuits
Features:
- High-speed operation: tpd = 4.6 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:
- Improved system performance due to high-speed operation.
- Reduced power consumption resulting in cooler operation and prolonged battery life.
- Compatibility with TTL logic simplifies interfacing with existing systems.
- Sufficient output drive capability allows for driving multiple devices.
- Predictable timing characteristics simplify circuit design.
- Reliable performance within a specified voltage range.
The TC74VHCT08FS consists of four independent 2-input AND gates. The output (Y) is high only when both inputs (A and B) are high; otherwise, the output is low. The device is designed to operate within a supply voltage range of 4.5V to 5.5V and is provided in an SOP package. Its TTL-compatible inputs make it an ideal choice for interfacing with TTL logic circuits.
