M38510/30103BEA

Overview

The M38510/30103BEA is a military-grade dual J-K negative-edge-triggered flip-flop manufactured by Texas Instruments. It operates within a supply voltage range of 4.5V to 5.5V, with quiescent current of 6 mA and output currents of 400µA (high) and 4mA (low). The maximum clock frequency is 45 MHz. The device features preset and clear inputs for direct control. It is housed in a 16-lead ceramic dual in-line package (CDIP-J) and supports an operating temperature range from -55°C to 125°C.

Feature Summary

• Dual independent J-K negative-edge-triggered flip-flops
• Direct preset and clear input functionality
• Military-grade reliability with extended temperature range

Applications

• Military aerospace digital logic systems
• High-reliability data storage circuits
• Industrial control state machines

Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs) before procurement. Confirm that the CDIP-J package meets mechanical constraints. Ensure the MIL-PRF-38535 Class B screening level aligns with project requirements. Validate supplier authorization for military-spec parts.

Selection Notes

Select this part for applications requiring negative-edge triggering and high noise immunity. Compare against positive-edge variants like M38510/30109BEA if timing polarity differs. Consider the 45 MHz limit for high-speed designs. Verify pin compatibility with existing footprints.

Part Context

This part belongs to the SN54LS series, representing the military version of the standard LS logic family. It provides enhanced performance over commercial grades while maintaining logical compatibility. The M38510 prefix indicates compliance with specific military procurement standards.

Replacement Considerations

M38510/30109BEA serves as a functional substitute but utilizes positive-edge triggering instead of negative-edge. Verify timing diagram requirements before substitution. Other SN54LS112 equivalents may lack the specific military packaging or screening levels.
