DESCRIPTION The M54HC157 is an high speed CMOS QUAD 2 CHANNEL MULTIPLEXER fabricated with silicon gate C2MOS technology.

These device consist of four 2-input digital multiplexer with common select and strobe inputs. When the STROBE input is held high, selection of data is inhibited 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 are equipped with protection circuits against static discharge and transient excess voltage.
