DUAL 2-TO-4 LINE DECODER

The TC74AC139 is an advanced high speed CMOS 2-to-4 LINE DECODER fabricated with silicon gate and double-layer metal wiring C2MOS 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 gating or it can be used as a data input for demultiplexing applications.
