74F139SCX

Signal Switches, Multiplexers, Decoders Overview

The onsemi 74F139SCX is a high-speed dual 1-of-4 decoder/demultiplexer housed in a 16-lead SOIC package. It contains two independent decoders, each accepting two binary weighted address inputs and providing four mutually exclusive active LOW outputs. The device operates within a supply voltage range of +4.5V to +5.5V and supports an ambient temperature range of 0°C to +70°C.
