Overview
The 100125J-MIL is a military-grade ECL to TTL translator manufactured by National Semiconductor. It operates within a temperature range of -55°C to 125°C and utilizes a 24-pin DIP ceramic package. The device converts ECL logic levels to TTL standards, ensuring compatibility between different logic families in high-reliability applications.
Feature Summary
- Military-grade reliability with MIL-STD-883 Class B screening
- Converts ECL signals to TTL logic levels
- Ceramic DIP packaging for harsh environment durability
Applications
- Military communication systems
- Avionics data buses
- High-reliability industrial control interfaces
Procurement Notes
Verify the specific revision level and screening class (MIL-STD-883) upon order confirmation. Ensure the supplier provides traceability documentation for the ceramic package and tin/lead termination. Confirm that the component meets the required environmental specifications for your application before finalizing procurement.
Selection Notes
Select this component when interfacing ECL sources with TTL destinations in environments requiring extended temperature operation. The ceramic package offers superior thermal stability compared to plastic alternatives. Consider pin count and form factor constraints when integrating into existing PCB layouts designed for 24-pin DIP footprints.
Part Context
This part belongs to National Semiconductor's legacy line of logic translators. It serves as a bridge between emitter-coupled logic and transistor-transistor logic families. The 'J' suffix typically denotes a military temperature range and ceramic construction, distinguishing it from commercial variants.
Replacement Considerations
Direct substitutes may include other National Semiconductor or Texas Instruments ECL-to-TTL translators in 24-pin DIP packages. Verify pinout compatibility and voltage level thresholds before substitution. Cross-reference with current TI datasheets for updated availability and equivalent performance metrics.
