JM38510/36001B2A

Overview

The JM38510/36001B2A is a priority encoder manufactured by Texas Instruments, designed for military and aerospace applications. It converts ten or eight input lines into binary-coded outputs. The device operates within an extended temperature range of -55 °C to 125 °C. It utilizes a 20-pin Leadless Ceramic Chip Carrier (LCCC) package designated as FK. This component belongs to the ALS logic family, ensuring compatibility with standard TTL interfaces while providing radiation-hardened performance characteristics suitable for harsh environments.

Feature Summary

• Converts decimal inputs to binary codes using priority encoding logic
• Operates reliably across extreme temperature ranges from -55 °C to 125 °C
• Utilizes hermetic ceramic packaging for environmental protection
• Compatible with standard TTL voltage levels

Applications

• Military avionics systems requiring radiation tolerance
• Aerospace data acquisition and control units
• Harsh environment industrial instrumentation
• High-reliability communication equipment

Procurement Notes

Verify the specific suffix B2A against official Texas Instruments documentation to confirm the exact pinout and electrical specifications. Ensure the LCCC FK package dimensions match your PCB footprint requirements. Confirm that the manufacturer source provides traceability certificates required for defense or aerospace procurement standards before finalizing orders.

Selection Notes

Select this component when a hardened priority encoder is required for high-temperature operation. The ALS series offers a balance of speed and power consumption. Verify that the 20-pin LCCC package is compatible with your assembly process. Consider the radiation hardness level if the application involves space or nuclear environments compared to commercial grade alternatives.

Part Context

This part falls under the JM38510 series, which defines military-grade integrated circuits. Texas Instruments produces these components to meet strict MIL-STD specifications. The ALS family designation indicates advanced low-power Schottky technology. These devices are intended for long-term reliability in critical systems where standard commercial parts may fail due to environmental stressors.

Replacement Considerations

Check for direct cross-reference part numbers from Texas Instruments or authorized distributors. Verify that any substitute maintains the same LCCC FK package and pin configuration. Ensure the replacement meets the -55 °C to 125 °C operating temperature range and radiation hardness requirements specified for the original design.
