Overview
The JM38510/65302SDA is a high-speed CMOS logic device belonging to the HC/UH series, manufactured by Texas Instruments. It functions as a dual positive-edge-triggered D flip-flop with clear inputs. The component supports an operating supply voltage range of 2V to 6V and features a ceramic flatpack package with 14 terminals. Designed for military specifications under MIL-M-38510 Class S, it operates reliably within an extended temperature range from -55°C to 125°C.
Feature Summary
- Dual positive-edge-triggered D flip-flop configuration
- High-speed CMOS technology compatible with standard logic families
- Military-grade reliability certified under MIL-M-38510 Class S standards
Applications
- Data storage registers in military communication systems
- Shift register arrays for signal processing
- Timing control circuits in aerospace avionics
Procurement Notes
Verify that the specific suffix 'SDA' corresponds to the required ceramic flatpack package variant and terminal finish. Confirm that the component meets the strict MIL-M-38510 Class S screening requirements necessary for defense applications. Ensure compatibility with existing board layouts requiring this specific package geometry and pinout configuration.
Selection Notes
Select this part when a dual D flip-flop with positive edge triggering is required in harsh environments. The HC/UH series offers high noise immunity and wide voltage tolerance suitable for varied power supplies. Consider the ceramic flatpack package for superior thermal performance and hermetic sealing compared to plastic alternatives in critical missions.
Part Context
This component is part of the broader JM38510 family, which encompasses various logic gates and flip-flops designed for high-reliability applications. The JM38510/65302SDA specifically addresses the need for sequential logic elements in systems where radiation hardness and temperature stability are paramount. It complements other devices in the series for complex digital circuit designs.
Replacement Considerations
Cross-reference with other manufacturers offering MIL-M-38510 qualified dual D flip-flops. Verify pinout compatibility and electrical characteristics against equivalent parts from Raytheon or Analog Devices before substitution.
