JM38510/30903BEA

Overview

The JM38510/30903BEA is a quadruple 2-line to 1-line data selector/multiplexer manufactured by Texas Instruments. It features a 16-pin ceramic dual in-line package (CDIP) designed for military-grade reliability. The device operates within an extended temperature range of -55°C to 125°C. Key electrical specifications include a propagation delay of 27ns, a supply voltage range of 4.5V to 5.5V, and a quiescent current of 400μA. It supports through-hole mounting with a height of 3.56mm.

Feature Summary

Quadruple 2-line to 1-line data selection capability
Military-grade ceramic dual in-line packaging
Extended operating temperature range from -55°C to 125°C

Applications

Military data routing systems
High-reliability signal multiplexing
Avionics control interfaces

Procurement Notes

Verify the specific revision code and manufacturer lot traceability when sourcing this component. Ensure the supplier provides documentation confirming compliance with the JM38510 military specification standards. Check for any lead-free or RoHS exemptions if required by your assembly process, as this is a legacy military part. Confirm the physical integrity of the ceramic package upon receipt.

Selection Notes

Select this component when high radiation tolerance and wide temperature stability are critical. It serves as a direct replacement for standard SN54LS157 variants in harsh environments. Consider the CDIP footprint constraints during PCB layout. Evaluate power consumption requirements against the 400μA quiescent current specification for battery-operated military applications.

Part Context

This part belongs to the SN54 series of logic devices, which are characterized by their military-grade construction and extended temperature ratings. It is functionally equivalent to the commercial SN54LS157 but utilizes robust ceramic packaging. The JM38510 prefix indicates compliance with specific military procurement standards, distinguishing it from general-purpose industrial logic components.

Replacement Considerations

Direct substitutes include other SN54LS157 variants in compatible packages. Verify pin compatibility before replacing. Cross-reference with MIL-PRF-38534 qualified sources for equivalent performance.
