SNJ54AS250AJT

Signal Switches, Multiplexers, Decoders Overview

The SNJ54AS250AJT is a military-grade 1-of-16 data selector/multiplexer in the AS logic series. It features full binary decoding to select one of sixteen inputs, providing an inverted output (W). The device includes buffered 3-state bus driver inputs and a buffered output-enable (OE) input for cascading or high-impedance isolation. It operates over the full military temperature range of -55°C to 125°C with a supply voltage of 4.5V to 5.5V. Key electrical characteristics include symmetrical propagation delays ranging from 2ns to 15.5ns depending on the signal path, and output currents of -12mA (high) and 32mA/48mA (low).

• Data source selection

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix 'JT' corresponds to the Ceramic Dual-In-Line package when sourcing. Confirm the component meets the required military temperature specifications (-55°C to 125°C) for your application environment. Ensure compatibility with the 4.5V to 5.5V supply voltage range. Check for RoHS exemption status if environmental compliance is mandatory for your assembly process.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a high-speed, military-rated multiplexer is required for systems operating in extreme temperatures. The AS series offers faster switching speeds compared to standard TTL or LS families. Consider the 3-state output capability if bus sharing or cascading multiple selectors is necessary. Verify that the 24-pin ceramic DIP package fits within the mechanical constraints of the target design.
