SNJ54HC237J

Signal Switches, Multiplexers, Decoders Overview

The SNJ54HC237J is a military-grade, radiation-hardened 3-to-8 line decoder with latched outputs manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V for the HC series and supports an ambient temperature range from -55°C to +125°C. The device utilizes a hermetic 16-lead ceramic dual in-line package (CDIP) designed for aerospace applications requiring single event latch-up immunity up to 110 MeV.cm²/mg and total ionizing dose hardness of 50 krad (Si).
