JM38510/34102BFA

Overview

The JM38510/34102BFA is a military-grade dual J-K positive-edge-triggered flip-flop manufactured by Texas Instruments. It belongs to the SN54F series, utilizing TTL-compatible inputs and featuring clear and preset functions. The component operates within a supply voltage range of 4.5 V to 5.5 V and supports a propagation delay of 10 ns. It is housed in a 16-pin Ceramic Flatpack (CFP) package, designed for through-hole mounting. The device ensures reliable performance across an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Dual J-K configuration with positive-edge triggering mechanism
• Integrated clear and preset control inputs for state management
• Military-grade construction compliant with MIL-STD specifications
• TTL-compatible input logic levels for standard interface

Applications

• High-reliability digital data storage systems
• Military aerospace sequential logic circuits
• Industrial control system state registers
• Defense communication equipment timing modules

Procurement Notes

Verify that the specific part number matches the required military qualification standards and package variant. Confirm compatibility with existing board layouts due to the ceramic flatpack form factor. Ensure sourcing channels provide valid traceability documentation for defense applications. Check current availability status as military components may have restricted distribution or long lead times compared to commercial equivalents.

Selection Notes

Select this component when dual J-K functionality with edge triggering is required in harsh environments. The SN54F series offers faster switching speeds than standard 74-series counterparts. Consider the 16-pin CFP package for robust mechanical stability in vibration-prone applications. Verify that the TTL input requirements align with the driving circuit's output capabilities to ensure signal integrity.

Part Context

This part is a military-specific variant of the SN54F109 dual J-K flip-flop. It adheres to strict quality and reliability standards mandated for defense electronics. The designation indicates compliance with specific government procurement specifications, distinguishing it from commercial grade logic ICs. It serves as a critical building block for complex sequential logic designs in regulated industries.

Replacement Considerations

Direct substitutes include other military-qualified SN54F109 variants such as JM38510/34102BEA. Verify pinout compatibility and electrical characteristics before substitution. Commercial equivalents like SN74F109 lack the necessary environmental ratings and must not be used in place of this military-grade component without rigorous validation.
