Overview
The JM38510/00204BEA is a military-grade dual J-K flip-flop manufactured by Texas Instruments. It features preset and clear functions, housed in a 16-lead ceramic flatpack (CFP) package. The device operates within a supply voltage range of 4.5 V to 5.5 V and supports an operating temperature range from -55°C to 125°C. It is designed for high-speed applications with frequencies up to 20 MHz.
Feature Summary
- Dual J-K flip-flop configuration with dedicated preset and clear inputs
- Military-grade reliability with extended temperature operation
- TTL-compatible input logic levels
Applications
- Military aerospace computing systems
- High-reliability digital storage circuits
- Sequential logic control in harsh environments
Procurement Notes
Verify component authenticity through authorized channels due to limited availability. Confirm that the received unit matches the specific JM38510/00204BEA designation and packaging requirements. Ensure handling procedures comply with military specifications for ceramic packages. Check for any special ordering constraints or factory-direct fulfillment requirements associated with this restricted supply item.
Selection Notes
Select this component when dual J-K flip-flops with preset and clear are required in military or industrial applications. Consider the 16-lead CFP package for thermal and mechanical robustness. Verify compatibility with existing TTL logic families and ensure the operating temperature range meets environmental demands. Evaluate space constraints against the physical dimensions of the ceramic flatpack.
Part Context
This part belongs to the JM38510 series, which encompasses various logic functions under military specifications. It is distinct from commercial counterparts like the SN54LS76A, offering enhanced durability and performance standards suitable for defense and aerospace sectors. The series ensures consistent quality across different logic types.
Replacement Considerations
The SN54LS76A is a documented equivalent functionally, though it may not meet all military qualification standards. Verify pinout compatibility and electrical characteristics before substitution. Ensure the replacement source provides necessary documentation for military compliance if required.
