MC74LCX139
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 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.
The MC74LCX139 high−speed 2−to−4 decoder/demultiplexer accepts two binary weighted inputs (A0, A1) and, when enabled, provides four mutually exclusiv...
