SNJ54LS158J

Signal Switches, Multiplexers, Decoders Overview

The SNJ54LS158J is a military-grade quadruple 2-line-to-1-line data selector/multiplexer manufactured by Texas Instruments. It operates within an extended temperature range of -55°C to +125°C and utilizes a 16-pin ceramic dual in-line package (CDIP). The device provides four independent multiplexers, each selecting one of two data inputs based on common select lines. It features complementary outputs for each channel.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix against the Package Option Addendum to confirm the exact package type and material specifications. Ensure the procurement documentation explicitly states QML certification status if required for your application. Confirm that the RoHS exemption aligns with your regulatory compliance requirements before finalizing the purchase order.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when military-grade environmental tolerance and long-term reliability are mandatory. The CDIP package offers robust mechanical integrity suitable for high-vibration environments. Verify that the LS logic family voltage levels meet the system interface requirements compared to standard catalog variants.

Signal Switches, Multiplexers, Decoders Part Context

This part belongs to the SN54LS158 series, which includes both commercial (SN74) and military (SN54) versions. The SNJ suffix specifically denotes the ceramic dual in-line package variant. It serves as a specialized alternative to plastic packaged devices, offering superior performance under extreme thermal conditions defined by military standards.

Signal Switches, Multiplexers, Decoders Replacement Considerations

Direct substitutes include other SNJ54LS158J units or equivalent military-qualified parts from authorized manufacturers. Commercial equivalents like SN74LS158N lack the required temperature range and reliability certifications.
