MC74VHC157 Description
MC74VHC157 Quad 2-Channel Multiplexer The MC74VHC157 is an advanced high−speed CMOS quad 2−channel multiplexer, fabricated with silicon gate CMOS technology. It achieves high−speed operation similar to equivalent Bipolar−Schottky TTL, while maintaining CMOS low−power dissipation. It consists of four 2−input digital multiplexers with mon select (S) and enable (E) inputs.
