74ACT14 - HEX SCHMITT INVERTER

General Description

The AC/ACT139 is a high-speed, dual 1-of-4 decoder/ demultiplexer.

The device has two independent decoders, each accepting two inputs and providing four mutuallyexclusive active-LOW outputs.

Each decoder has an active-LOW Enable input which can be used as a data input for a 4-output demultiplexer.
