DESCRIPTION The 74AC158 is an advanced high-speed CMOS QUAD 2-CHANNEL MULTIPLEXER (INVERTING) 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 an inverting

multiplexer. When the STROBE input is held high selection of data is inhibit and all the outputs become high. 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.
