SNJ54ALS157AJ

Signal Switches, Multiplexers, Decoders Overview

The SNJ54ALS157AJ is a military-grade dual 1-of-4 data selector/multiplexer housed in a 16-pin ceramic DIP package. It selects a 4-bit word from one of two sources and routes it to four outputs. The device features buffered inputs and outputs with a separate strobe input for control. It operates over the full military temperature range of -55°C to 125°C with a supply voltage of 4.5V to 5.5V.

Signal Switches, Multiplexers, Decoders Feature Summary

• Provides full data selection capability through integrated inverters and drivers connected to four output gates.
• Includes a dedicated strobe input to manage data routing between two distinct source options.
• Delivers true data presentation at the outputs without inversion.

Signal Switches, Multiplexers, Decoders Applications

• Military-grade digital data routing systems
• High-reliability aerospace signal multiplexing
• Defense communication equipment data selection

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify that the component matches the specific SNJ54ALS157AJ part number, as suffixes indicate package type and temperature rating. Confirm the presence of the military grade designation and ceramic packaging. Ensure documentation aligns with Texas Instruments specifications for this exact variant before procurement.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when military temperature stability and high reliability are required. It is suitable for applications needing true data output without inversion. Compare against SN54ALS158 variants if inverted output functionality is necessary instead of true data presentation.

Signal Switches, Multiplexers, Decoders Part Context

This device belongs to the Texas Instruments ALS logic family, designed for advanced low-power Schottky applications. The SNJ prefix denotes a military-grade ceramic package variant, distinguishing it from commercial plastic packages or standard SN54 series parts.

Signal Switches, Multiplexers, Decoders Replacement Considerations

SNJ54ALS158AJ provides inverted data output instead of true data. SN54ALS157AJ offers identical functionality but may differ in specific military qualification markings.
