... MC74VHC139 Dual 2−to−4 Decoder/ Demultiplexer The MC74VHC139 is an advanced high speed CMOS 2−to−4 decoder/ demultiplexer fabricated with silicon gate CMOS technology. It achieves high speed operation similar to equivalent Bipolar Schottky TTL while maintaining CMOS low power dissipation. When the device is enabled (E = low), it can be used for gating data input for demultiplexing operations ...
