SNJ54LS153FK

Signal Switches, Multiplexers, Decoders Overview

The SNJ54LS153FK is a dual 1-of-4 data selector/multiplexer manufactured by Texas Instruments. It operates within a military-grade temperature range of -55°C to 125°C and utilizes a 20-pin Leadless Ceramic Chip Carrier (LCCC) package designated as FK. The device contains two independent multiplexers, each featuring four data inputs, two select lines, one enable input, and one true output. This component belongs to the LS logic series and is designed for high-reliability applications requiring extended environmental tolerance.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix FK to confirm the LCCC package type. Confirm RoHS exemption status as indicated in official documentation. Ensure the procurement channel provides traceability for military-grade components. Validate that the supplier handles leadless ceramic packages appropriately to prevent mechanical damage during handling.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when dual 4-to-1 multiplexing is required in environments exceeding standard commercial temperature limits. The LCCC package is suitable for applications demanding high thermal conductivity and hermetic sealing capabilities. Consider the pin count and layout requirements associated with the 20-pin ceramic carrier during PCB design.

Signal Switches, Multiplexers, Decoders Part Context

This part is part of the SN54LS153 family, which includes variants in CDIP and CFP packages. The SNJ prefix indicates a military qualification level. Other versions such as SN74LS153 are available for commercial temperature ranges. The FK suffix specifically denotes the 20-pin LCCC form factor distinct from the 16-pin DIP options.
