JM38510/30903B2A

Overview

The JM38510/30903B2A is a 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 20-pin LCCC (FK) ceramic package. The device features four independent channels, each capable of selecting one of two data inputs based on control signals. Key electrical specifications include a maximum operating frequency of 35 MHz and a maximum supply current of 16 mA.

Feature Summary

Provides four independent multiplexing channels for data routing
Operates reliably in extreme industrial and military temperature environments
Utilizes hermetically sealed ceramic packaging for durability

Applications

High-reliability digital data selection systems
Military aerospace signal routing
Industrial control data multiplexing

Procurement Notes

Verify the specific suffix 'B2A' against official Texas Instruments documentation to confirm pinout and functional compatibility. Ensure the procurement source provides traceability to MIL-PRF-38534 standards, as this part number denotes a qualified military-grade component. Confirm package integrity upon receipt.

Selection Notes

Select this component when high-density multiplexing is required in harsh environments. The LCCC package offers superior thermal stability compared to plastic alternatives. Consider the 35 MHz speed limit and 16 mA current draw during system power budgeting. Verify that the 20-pin footprint matches the target PCB design constraints.

Part Context

This part belongs to the SN54LS157 family, representing the military-grade version of the standard LS TTL quad multiplexer. It shares functional equivalence with commercial variants but meets stricter reliability and environmental testing criteria defined by Texas Instruments for defense applications.

Replacement Considerations

Direct substitutes include other SN54LS157 variants with compatible military suffixes. Verify pin-to-pin compatibility before substitution. Cross-reference with manufacturer-approved alternates to ensure identical electrical characteristics and package dimensions.
