DESCRIPTION The 74AC157 is an advanced high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS tecnology. It consists of four 2-input digital multiplexer with common SELECT and STROBE inputs. It is a non-inverting multiplexer. When the STROBE

input is held high selection of data is inhibit and all the outputs become low. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. All inputs and outputs are equipped with protection circuits against static discharge, giving them 2KV ESD immunity and transient excess voltage.
