TC74HCT157AP/AF TOSHIBA CMOS Digital Integrated Circuit Silicon Monolithic TC74HCT157AP, TC74HCT157AF Quad 2-Channel Multiplexer The TC74HCT157A is a high speed CMOS 2-CHANNEL MULTIPLEXERs fabricated with silicon gate C2MOS technology. It achieves the high speed operation similar to equivalent LSTTL while maintaining the CMOS low power dissipation. This device may be used as a level converter for interfacing TTL or NMOS to High Speed CMOS. The inputs are compatible with TTL, NMOS and CMOS output voltage levels. When STROBE 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 transferred to their corresponding Y outputs.
