SNJ54AHC138W

Signal Switches, Multiplexers, Decoders Overview

The SNJ54AHC138W is a military-grade 3-line to 8-line decoder/demultiplexer from the AHC series, housed in a 16-pin ceramic flatpack (CFP) package. It operates within a supply voltage range of 2V to 5.5V and supports an extended temperature range of -55°C to 125°C. The device features three enable inputs (two active-low, one active-high) for simplified cascading and includes high ESD protection ratings exceeding 2000V via the human-body model.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the 16-pin Ceramic Flatpack (CFP) package configuration. Confirm that the military grade designation requires adherence to MIL-PRF-38535 or equivalent qualification standards if applicable to your procurement requirements. Ensure compatibility with the specified operating temperature range and voltage parameters before finalizing orders.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when military-grade reliability and wide temperature operation are required alongside high-speed logic performance. The AHC technology offers faster switching speeds compared to standard HC series devices while maintaining CMOS power efficiency. Consider the CFP package for applications necessitating hermetic sealing or specific mechanical mounting constraints associated with ceramic packages.
