The MC74LCX157 is a high performance, quad 2−input multiplexer operating from a 2.3 to 3.6 V supply. High impedance TTL compatible inputs significantly reduce current loading to input drivers while TTL compatible outputs offer improved switching noise performance. A VI specification of 5.5 V allows MC74LCX157 inputs to be safely driven from 5 V devices.
