Overview
74VHC138 3-to-8 Decoder/Demultiplexer November 1992 Revised April 1999 74VHC138 3-to-8 Decoder/Demultiplexer General Description 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 (A0, A1 and A2) determine which one of the outputs (O0–O7) will go LOW.
When enable input E3 is held LOW or either E1 or E2 is held HIGH, decoding function is inhibited and all outputs go HIGH.
E3, E1 and E2 inputs are provided to ease cascade connection and for use as ...
