Overview
The SN74HC139NG4 is a high-performance integrated circuit designed by Texas Instruments, belonging to the 74HC series. This device is a 1-of-4 decoder/demultiplexer, featuring two individual 2-line to 4-line decoders in a single package. It is optimized for high-speed memory-decoding or data-routing applications, requiring very short propagation delay times. The active-low enable (G) input can be used as a data line in demultiplexing applications, and the decoders/demultiplexers have fully buffered inputs, each representing only one normalized load to its driving circuit.
