Dual Low-Voltage CMOS 2-to-4 Decoder/Demultiplexer With 5V−Tolerant Inputs

The MC74LCX139 is a high performance, 2−to−4 decoder/demultiplexer 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 MC74LCX139 inputs to be safely driven from 5 V devices. The MC74LCX139 is suitable for memory address decoding and other TTL level bus oriented applications.
