3-to-8 Line Decoder

The TC74VHC138 is an advanced high speed CMOS 3-to-8

DECODER fabricated with silicon gate C2MOS technology.

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the 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 low.

When enable input G1 is held low or eitherG2A or G2B is held

high, decoding function is inhibited and all outputs go high.

G1, G2A , and G2B inputs are provided to ease cascade

connection and for use as an address decoder for memory

systems.

An input protection circuit ensures that 0 to 5.5 V can be

applied to the input pins without regard to the supply voltage.

This device can be used to interface 5 V to 3 V systems and two

supply systems such as battery back up. This circuit prevents

device destruction due to mismatched supply and input voltages.
