JM38510/37701BEA

Overview

The JM38510/37701BEA is a military-grade 3-line to 8-line decoder/demultiplexer from Texas Instruments. It belongs to the ALS logic family and operates within a temperature range of -55°C to 125°C. The device features a ceramic metal-sealed cofired package with 14 pins in a CDIP configuration. It converts three binary input lines into eight distinct output lines, providing high-speed performance suitable for demanding environments.

Feature Summary

• Converts three independent input signals into eight mutually exclusive output lines
• Constructed with a hermetically sealed ceramic metal body for environmental protection
• Engineered for extended operational stability across extreme industrial temperature ranges

Applications

• Military communication systems requiring reliable signal routing
• Avionics data bus decoding architectures
• Spacecraft telemetry control circuits

Procurement Notes

Verify the specific suffix designation against official Texas Instruments documentation to confirm exact electrical characteristics and qualification standards. Ensure the component meets all required military specifications before integration. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability records.

Selection Notes

Select this component when a robust, radiation-hardened capable decoder is required for critical infrastructure. The ALS series offers a balance of speed and power consumption. Confirm that the CDIP package dimensions fit the designated footprint and that the thermal management strategy supports the specified operating temperature limits.

Part Context

This part is part of the 54ALS138A family, representing a standardized decoder design adapted for military reliability. It serves as a direct replacement for standard commercial equivalents in harsh environments. The JM38510 prefix indicates compliance with specific military procurement standards defined by the Defense Logistics Agency.

Replacement Considerations

Direct substitutes include other 54ALS138A variants from qualified manufacturers. Verify pin compatibility and voltage levels before substitution. Ensure any alternative maintains the same ceramic packaging and temperature rating for equivalent performance.
