ST M74HCT157 QUAD 2 CHANNEL MULTIPLEXER handbook
The document introduces the M74HCT157, which is a high-speed CMOS quad 2-input digital multiplexer. It features high speed, low power dissipation, compatibility with TTL outputs, etc. The device consists of four 2-input digital multiplexers with common select and strobe inputs. When the STROBE input is held high, data selection 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.
