JM38510/65652BSA

Overview

The JM38510/65652BSA is an octal D-type flip-flop manufactured by Texas Instruments, designed for military and aerospace applications under the MIL-M-38510 specification. It features eight non-inverting D-type flip-flops with three-state outputs, allowing for efficient bus-oriented memory and data transmission. The device operates within a temperature range of -55°C to 125°C and utilizes a 20-pin ceramic flatpack (CFP) package. Key electrical characteristics include a supply voltage range typical of TTL logic, with defined propagation delays and output drive capabilities suitable for high-reliability digital systems.

Feature Summary

• Octal configuration providing eight independent D-type flip-flops in a single package
• Three-state outputs enable direct bus interfacing without additional buffering
• Non-inverting logic function ensures signal polarity preservation
• Military-grade construction supports operation in extreme thermal environments

Applications

• High-reliability military avionics data storage
• Aerospace telemetry signal latching
• Ruggedized industrial control system memory registers
• Defense communication equipment data buffers

Procurement Notes

Verify that the component meets the specific MIL-M-38510 class requirements for your application. Confirm the package type and pinout compatibility with existing board layouts. Check for any required quality certifications or traceability documentation mandated by defense contracts. Ensure the supplier provides valid source documentation for the part number to guarantee authenticity and performance standards.

Selection Notes

Select this component when an octal latch with tri-state capability is required for space-constrained, high-reliability designs. Consider the ceramic flatpack package for superior thermal and mechanical stability compared to plastic alternatives. Evaluate the propagation delay specifications against system timing constraints. Ensure the power supply architecture supports the current requirements of multiple three-state outputs simultaneously.

Part Context

This part belongs to the JM38510 series, which encompasses various logic functions qualified for military use. It represents a specialized variant focusing on sequential logic rather than combinational gates. The designation indicates compliance with specific military standards for durability and performance consistency across harsh operational conditions.

Replacement Considerations

Direct replacements must match the octal D-flip-flop topology and three-state output configuration. Verify pin-for-pin compatibility with the 20-pin CFP package. Ensure equivalent electrical parameters, including propagation delay and output drive strength, are met. Cross-reference with other MIL-M-38510 qualified parts from Texas Instruments or authorized manufacturers.
