Dual 2-to-4 Line Decoder

line decoder/demultiplexer fabricated with silicon gate C

technology.

bipolar schottky TTL while maintaining the CMOS low power

dissipation.

used as a data input for demultiplexing applications.

at a high logic level independent of the other inputs.

V to 5 V system.

be applied to the input and output

destruction due to mismatched supply and input/output voltages such as battery back up, hot board insertion, etc.

Features

•

The TC7MET139AFK is an advanced high speed CMOS 2 to 4

It achieves the high speed operation similar to equivalent

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

When the enable input is held High, all four outputs are fixed

The input voltage are compatible with TTL output voltage.

This device may be used as a level converter for interfacing 3.3

Input protection and output circuit ensure that 0 to 5.5 V can
