Overview
The JM38510/37204BRA is an octal D-type edge-triggered flip-flop manufactured by Texas Instruments. It features three-state outputs and is housed in a 20-pin ceramic dual in-line package (CDIP). The device operates within a military-grade temperature range of -55°C to 125°C. It belongs to the LS series, designed for high-speed digital applications requiring reliable data storage and transfer capabilities under extreme environmental conditions.
Feature Summary
- Octal configuration providing eight independent D-type edge-triggered flip-flops
- Three-state output capability allowing direct bus interfacing
- Military-grade reliability with ceramic metal-sealed co-fired packaging
- Wide operating temperature range suitable for harsh environments
Applications
- High-reliability military aerospace digital systems
- Industrial control systems requiring extended temperature tolerance
- Data storage registers in ruggedized computing hardware
- Signal processing circuits in defense communication equipment
Procurement Notes
Verify that the component matches the exact JM38510/37204BRA designation, as this specific part number indicates MIL-PRF-38535 Class B qualification. Ensure the package is the 20-CDIP variant with ceramic construction. Confirm the manufacturer is Texas Instruments or an authorized source. Check for proper handling procedures due to the sensitive nature of military-grade semiconductor components.
Selection Notes
Select this component when octal data storage with tri-state output control is required in extreme thermal environments. It is appropriate for designs needing LS series speed characteristics combined with military durability. Consider the 20-CDIP footprint for PCB layout compatibility. Evaluate system requirements against the -55°C to 125°C operational range to ensure suitability for the intended application environment.
Part Context
This component is part of Texas Instruments' military semiconductor portfolio, adhering to strict quality standards. It serves as a critical logic element in complex digital circuits where data integrity and environmental resilience are paramount. The JM38510 series represents a standardized approach to high-performance logic functions for defense and aerospace sectors.
Replacement Considerations
Direct substitutes may include other qualified octal D-type flip-flops with three-state outputs from the same military specification family. Verify pinout compatibility and electrical parameters before substitution. Cross-reference with equivalent parts like those in the 54LS series if military qualification is not strictly required.
