Low-Voltage CMOS 3-to-8 Decoder/Demultiplexer With 5 V−Tolerant Inputs

The MC74LCX138 is a high performance, 3−to−8 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 MC74LCX138 inputs to be safely driven from 5 V devices. The MC74LCX138 is suitable for memory address decoding and other TTL level bus−oriented applications.

Current drive capability is 24 mA at the outputs.
