They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. These devices consist of four 2-input digital multiplexers with common select and strobe inputs. The HC158 is an inverting multiplexer while the HC157 is a non-inverting multiplexer. When the STROBE input is held High, selection of data is inhibited and all the outputs become Low in the M74HC157 and High in the M74HC158. 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.
