They achieve the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. The TC74HC158A is an inverting multiplexer while the TC74HC157A is a non-inverting. When STROBE is held high, selection of data is inhibited and all the outputs become low in the case of HC157A or high in the case of HC158A.
