74VHC138 Datasheet (Fairchild Semiconductor) - 3-to-8 Decoder/Demultiplexer

74VHC138, 3-to-8 Decoder/Demultiplexer

The VHC138 is an advanced high speed CMOS 3-to-8 decoder/demultiplexer fabricated with silicon gate CMOS 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
