The TC74VHC08FT(EL) is a high-speed CMOS quad 2-input AND gate manufactured by Toshiba. As part of the VHC (Very High-Speed CMOS) family, it offers the speed characteristics of bipolar logic gates with the low power consumption typical of CMOS technology. The device comprises four independent 2-input AND gates. The output of each gate is HIGH only when both of its inputs are HIGH; otherwise, the output is LOW.

Applications

• Digital systems
• Data processing
• Instrumentation and control systems
• Interface logic
• General-purpose logic circuits

Features

• High-speed operation: tpd = 4.1 ns (typ.) at VCC = 5 V
• Low power dissipation: ICC = 2 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 = 8 mA (min.)
• Balanced propagation delays: tPLH ≈ tPHL
• Wide operating voltage range: VCC = 2 V to 5.5 V
• Pin and function compatible with 74LS08

Benefits

• Enables faster system performance.
• Reduces power consumption, leading to cooler operation and extended battery life.
• Provides reliable operation in noisy environments.
• Allows direct interfacing with TTL logic.
• Simplifies circuit design with minimal timing skew.
• Offers flexibility in power supply selection.
• Easy replacement of older TTL logic devices.

Additional Details

The TC74VHC08FT(EL) comes in a TSSOP (Thin Small Outline Package). The (EL) suffix typically refers to specific environmental compliance or packaging details, which should be confirmed in the manufacturer's datasheet. It operates over a temperature range of -40°C to +85°C. This AND gate is suitable for many digital logic applications where speed and low power consumption are crucial.
