TC74VHC238FT Description

Short technical summary and product information.

The Toshiba TC74VHC238FT is an advanced high-speed CMOS 3-to-8 decoder fabricated with silicon gate C2MOS technology. It achieves high-speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation.

 

When the device is enabled, 3 binary select inputs (A, B, and C) determine which one of the outputs (Y0-Y7) will go high. Decoding is inhibited, and all outputs go low when the enable input G1 is held low or either A2G or 2BG is held high. Enable inputs G1, A2G, and 2BG are provided for easy cascade connection and use as an address decoder for memory systems.

 

This decoder features a wide operating voltage range from 2V to 5.5V and a typical propagation delay of 5.5 ns at 5V. It also boasts low power dissipation with a maximum quiescent current of 4 μA at 25°C. An input protection circuit allows 0 to 5.5V to be applied to the input pins without regard to the supply voltage, preventing device destruction due to mismatched supply and input voltages. This makes it suitable for interfacing 5V to 3V systems and two-supply systems.

 

The TC74VHC238FT is available in an SOP package and is designed for SMD mounting. It operates within an industrial temperature range of -40°C to 85°C.
