Overview
The 100302J-QMLV is a configurable NOR/OR gate circuit manufactured by National Semiconductor, now part of Texas Instruments. It belongs to the 100K series and features five functional units with two inputs each, designed for ECL logic applications. The device operates within a supply voltage range of 4.2V to 5.7V and is housed in a 24-DIP package with a 0.400-inch (10.16mm) width. This component is engineered for through-hole mounting and supports high-reliability environments.
Feature Summary
- Configurable multi-function logic architecture supporting both NOR and OR gate configurations
- ECL-compatible operation for high-speed digital processing requirements
- Military-grade qualification ensuring reliability in demanding operational conditions
Applications
- High-speed digital signal processing systems
- Aerospace and defense electronic control units
- Radar and communication system logic interfaces
Procurement Notes
Verify the manufacturer origin carefully, as National Semiconductor was acquired by Texas Instruments. Ensure the specific QMLV suffix matches your radiation hardness or military qualification requirements. Confirm the DIP-24 package dimensions align with your PCB footprint design. Request official datasheets from authorized distributors to validate current production status and authenticity before procurement.
Selection Notes
Select this component when ECL logic speed is required alongside configurable gate functionality. The five independent two-input structures allow flexible logic implementation without additional external components. Consider the 24-DIP package constraints for board space. Verify that the 4.2V to 5.7V supply range fits your system power architecture. Evaluate thermal management needs for through-hole mounting in enclosed enclosures.
Part Context
This component falls under the National Semiconductor 100K series, which provides high-speed ECL logic solutions. The QMLV designation indicates a qualified version suitable for military and aerospace applications. As a legacy product from National Semiconductor, it remains relevant in systems requiring proven radiation tolerance and long-term availability in ceramic or plastic DIP packages.
Replacement Considerations
Check for direct equivalents in the Texas Instruments portfolio following the acquisition. Verify pin compatibility and logical function mapping if substituting with other ECL gates. Ensure any replacement maintains the same voltage and temperature specifications.
