74AC153SJ

Signal Switches, Multiplexers, Decoders Overview

The Fairchild Semiconductor 74AC153SJ is a high-speed dual 4-input multiplexer belonging to the AC series. It features common select inputs and individual enable inputs for each section, allowing the selection of two lines of data from four sources. The device provides buffered outputs in true (non-inverted) form. It operates within a supply voltage range of 2V to 6V and supports an output drive current of 24mA. The component is housed in a 16-lead Small Outline Package (SOIC).
