JD54LS151SFA

Overview

The JD54LS151SFA is an 8-to-1 data selector/multiplexer manufactured by National Semiconductor. It operates within a supply voltage range of 4.75 V to 5.25 V, with a nominal rating of 5 V. The device supports a wide operating temperature range from -55 °C to 125 °C, suitable for military-grade applications. It features a 16-pin Ceramic Flat Pack (CFP) package with through-hole terminals and a pitch of 2.54 mm. The component utilizes LS-TTL technology and provides complementary outputs.

Feature Summary

• Provides high-speed signal routing capabilities for logic applications
• Selects one of eight data inputs for output transmission
• Constructed in a ceramic flat pack package for durability

Applications

• Logic circuit signal routing
• Data selection systems
• Multiplexing operations

Procurement Notes

Verify the specific suffix 'SFA' confirms the 16-pin Ceramic Flat Pack package type. Ensure compatibility with MIL-spec temperature ranges (-55 °C to 125 °C) if required. Confirm lead/tin terminal composition matches system requirements. Validate that the LS-TTL input/output levels align with the target logic family. Check for RoHS status as indicated by certification codes.

Selection Notes

Choose this component when a robust, military-grade multiplexer is required for harsh environments. The ceramic construction offers superior thermal stability compared to plastic packages. Ensure the design accommodates the 16-pin CFP footprint and through-hole mounting constraints. Verify that the 8-input configuration fits the data path architecture without excessive gating.

Part Context

This part belongs to the 54LS151 series of data selectors/multiplexers. It shares functional similarities with other variants like the 54LS151DM and SNJ54LS151J but differs in packaging. While the DM variant uses a DIP package and the J variant uses a CDIP, the SFA variant specifically utilizes a Ceramic Flat Pack form factor.

Replacement Considerations

Direct substitutes include parts sharing the 54LS151 base function and CFP package, such as the JD54LS151SFA itself from different distributors. Cross-referencing with SNJ54LS151J requires verifying package compatibility, as it typically uses a CDIP format rather than CFP.
