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.
