The TC74HCT08AF/EL is a high-speed CMOS quad 2-input AND gate with TTL-compatible inputs manufactured by Toshiba Semiconductor and Storage. It combines the high speed of the HC series with the TTL input voltage compatibility. It consists of four independent 2-input AND gates.
Applications
- General-purpose logic circuits
- AND gate logic functions
- System glue logic
- Digital signal processing
- Control systems
Features
- High-speed operation: tpd = 15 ns (typ.) at VCC = 5V
- Low power dissipation: ICC = 4 μA (max.) at Ta = 25°C
- TTL input voltage compatibility: VIH = 2.0 V (min.), VIL = 0.8 V (max.)
- Output drive capability: 10 LSTTL loads
- Symmetrical output impedance: |IOH| = IOL = 4 mA (min.)
- Wide operating voltage range: VCC = 4.5 V to 5.5 V
- Pin and function compatible with 74HCT08
Benefits
- High-speed performance enables use in applications requiring fast logic operations.
- Low power consumption reduces the overall power requirements of the system.
- TTL input compatibility allows for easy interfacing with TTL logic devices.
- Large output drive capability allows direct interfacing with various loads.
- Simplified design due to pin compatibility with the industry-standard 74HCT08.
Additional Details
The TC74HCT08AF/EL 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 both inputs A and B are HIGH. The 'HCT' designation indicates that it is a high-speed CMOS device with TTL-compatible input thresholds. The /EL suffix likely indicates a specific tape and reel packaging option. The package is a SOP14.
