Description

This circuit features dual 1-line-to-4-line demultiplexer with individual strobes and common binary-address input.

When both sections are enabled by the strobes, the common binary-address inputs sequentially select and route

associated input data to the appropriate output of each section. The individual strobes permit activating or inhibiting

each of the 4-bit sections as desired. Data applied to input 1C is inverted through its outputs. The inverter following

the 1C data input permits use as a 3-to-8-line decoder or 1-to-8-line demultiplexer without external gating.

Features

• High Speed Operation: t

• High Output Current: Fanout of 10 LSTTL Loads

• Wide Operating Voltage: V

• Low Input Current: 1 µA max

• Low Quiescent Supply Current: I
