SNJ54LS258BFK

Signal Switches, Multiplexers, Decoders Overview

The SNJ54LS258BFK is a quadruple 1-of-2 data selector/multiplexer from the LS series, manufactured by Texas Instruments. It features true outputs and operates within an extended temperature range of -55°C to 125°C. The component utilizes a 20-pin LCCC package (LCC20). Key electrical parameters include a maximum output current of 24 mA and a load capacitance of 45 pF. It functions as a single functional unit with two ports, designed for bidirectional or unidirectional signal routing in military-grade applications.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the manufacturer origin carefully, as listings may attribute this part to third-party entities like Tachyonics despite TI branding. Confirm the package type is LCCC-20 and check RoHS compliance status, as LS series parts are often non-compliant. Ensure the datasheet matches the specific SNJ prefix requirements for your application.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when quadruple 1-of-2 multiplexing is required in harsh environments. The LS series offers standard TTL compatibility. Consider the 24 mA sink current for driving loads. Verify that the true output polarity meets system logic requirements compared to inverted alternatives.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SNJ family, indicating military-grade qualification. It is distinct from commercial variants by its extended temperature range and rigorous testing standards. The LS designation places it in the Low-power Schottky TTL category, balancing speed and power consumption for robust digital logic applications.

Signal Switches, Multiplexers, Decoders Replacement Considerations

The SNJ54HC258FK is a documented alternative offering similar quadruple 1-of-2 functionality with 3-state outputs. Verify voltage level compatibility between HC and LS families before substitution.
