JM38510/32501BRA

Overview

The JM38510/32501BRA is a military-grade octal D-type flip-flop manufactured by Texas Instruments. It contains eight individual flip-flops with single-rail outputs, buffered clock inputs, and direct clear functionality. The device operates within a temperature range of -55°C to 125°C and utilizes a 20-pin ceramic dual in-line package (CDIP). It features a propagation delay of 27 ns at 5V and draws a maximum supply current of 85 mA. This component serves as a high-reliability alternative to the commercial SN54LS273.

Feature Summary

• Contains eight independent D-type flip-flops with single-rail outputs
• Includes buffered clock inputs and direct clear control for each stage
• Constructed with glass-sealed ceramic packaging for environmental durability

Applications

• Military aerospace data storage systems
• High-reliability industrial logic control circuits
• Harsh environment digital signal processing interfaces

Procurement Notes

Verify that the received component matches the exact part number JM38510/32501BRA, including any suffixes such as .A, as these may indicate specific manufacturing lot variations or testing standards. Confirm the package type is CDIP-20 and ensure the supplier provides traceability documentation required for military specifications. Check for physical damage to the ceramic housing before integration into sensitive applications.

Selection Notes

Select this component when designing systems requiring MIL-STD compliance and extended temperature operation beyond standard commercial limits. It is suitable for applications needing parallel data latching with synchronous clearing capabilities. Ensure the design accommodates the 20-pin CDIP footprint and accounts for the specified 85 mA maximum supply current during power budget calculations.

Part Context

This part belongs to the Texas Instruments JM38510 series, which covers military high-reliability integrated circuits. It corresponds functionally to the SN54LS273 octal D-type flip-flop but meets stricter qualification standards. The series supports critical applications where failure is not an option, providing robust performance in extreme thermal conditions.

Replacement Considerations

Direct substitutes include other manufacturers' equivalents meeting the same MIL-PRF-38510 specifications. Verify pin compatibility and electrical characteristics against the original datasheet before substitution. Generic LS-TTL alternatives may not meet the required temperature or reliability standards.
