The Toshiba 74VHC138FT is an advanced, high-speed CMOS 3-to-8 line decoder fabricated using silicon gate C2MOS technology. It achieves high-speed operation comparable to bipolar Schottky TTL while maintaining low CMOS power dissipation.
This decoder features a wide operating voltage range from 2V to 5.5V, making it suitable for interfacing between 5V and 3V systems. It includes input protection circuitry that prevents damage from mismatched supply and input voltages. Key features include high speed with a typical propagation delay of 5.7 ns at 5V, low power dissipation with a maximum supply current of 4μA at 25°C, and high noise immunity.
The device has three binary select inputs (A, B, and C) that determine which of the eight outputs (0Y-7Y) will go low when enabled. The enable inputs (G1, 2AG, and 2BG) allow for easy cascade connection and use as an address decoder in memory systems. All inputs are protected against device destruction due to mismatched supply and input voltages.
The 74VHC138FT is supplied in a 16-TSSOP package, suitable for surface mounting. It is pin and function compatible with the 74ALS138.
