Datasheet Summary
Dual Low-Voltage CMOS 2-to-4 Decoder/Demultiplexer
With 5 V- 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 patible inputs significantly reduce current loading to input drivers while TTL patible 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.
The MC74LCX139 high- speed 2- to- 4 decoder/demultiplexer accepts two binary weighted inputs (A0, A1) and, when enabled, provides four mutually...
