74VHC139 Dual 2-to-4 Decoder/Demultiplexer

The VHC139 is an advanced high speed CMOS Dual 2-to4 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. The active LOW enable input can be used for gatin.
