Product Summary

The 74ACT157D is a quad 2 channel multiplexer fabricated with sub-micron silicon gate and double-layer metal wiring C2MOS technology. It is ideal for low power applications maintaining high speed operation similar to equivalent Bipolar Schottky TTL. The 74ACT157D consists of four 2-input digital multiplexers with common select and strobe inputs. It is a non-inverting multiplexer. When the STROBE input is held High selection of data is inhibit and all the outputs become low. The SELECT decoding determines whether the A or B inputs get routed to their corresponding Y outputs. The 74ACT157D is designed to interface directly High Speed CMOS systems with TTL, NMOS and CMOS output voltage levels.
