xer With 5V-Tolerant Inputs MC74LCX138 The MC74LCX138 is a high performance, 1–of–8 decoder/ demultiplexer operating from a 2.7 to 3.6V 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 5.5V allows MC74LCX138 inputs to be safely driven from 5V devices. The MC74LCX138 is suitable for memory address decoding and other TTL level bus oriented applications. The MC74LCX138 high–speed 1–of–8 decoder/demultiplexer accepts three binary weighted inputs (A0, A1, A2) and, when enabled, provide
