SNJ54F158AJ

Signal Switches, Multiplexers, Decoders Overview

The SNJ54F158AJ is a quadruple 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It features four independent multiplexers, each capable of selecting one of two data inputs based on a common select line. The device utilizes the F/FAST logic series and is housed in a 16-lead ceramic dual in-line package (CDIP). It operates within a military-grade temperature range of -55°C to 125°C.
