Dual 2-to-4 Line Decoder

The TC74ACT139 is an advanced high speed CMOS 2 to 4

LINE DECODER fabricated with silicon gate and double-layer

It achieves the high speed operation similar to equivalent

Bipolar Schottky TTL while maintaining the CMOS low power

dissipation.

This device may be used as a level converter for interfacing

TTL or NMOS to High Speed CMOS. The inputs are compatible

with TTL, NMOS and CMOS output voltage levels.

The active low enable input can be used for gating or it can be

used as a data input for demultiplexing applications.

When the enable input is held “H”, all four outputs are fixed at

a high logic level independent of the other inputs.

All inputs are equipped with protection circuits against static

discharge or transient excess voltage.
