Overview
The 95H28DC is a dual D-type flip-flop integrated circuit manufactured by National Semiconductor. It utilizes Emitter-Coupled Logic (ECL) technology to provide high-speed data storage and transfer capabilities within digital systems. The component integrates two independent D flip-flops into a single package, facilitating efficient design for applications requiring rapid clocked data handling. This specific part number represents the standard commercial grade version of the device.
Feature Summary
- Dual D-type flip-flop configuration in a single package
- Emitter-Coupled Logic (ECL) construction for high-speed operation
Applications
- High-speed digital data storage circuits
- Clock synchronization systems
- Digital signal processing interfaces
Procurement Notes
Verify the manufacturer marking matches National Semiconductor specifications. Confirm the package type aligns with system board requirements. Check for RoHS compliance status if environmental regulations apply. Ensure the voltage supply range matches the ECL logic level standards required by the application design.
Selection Notes
Select this component when ECL speed is critical for dual-channel data latching. Consider thermal management due to ECL power characteristics. Evaluate pin compatibility with existing footprints. Verify that the operating temperature range meets the environmental conditions of the target deployment scenario.
Part Context
National Semiconductor produced this ECL logic family before its acquisition by Texas Instruments. The 95H28DC belongs to the legacy high-speed logic series. These components are often used in retrofits or maintenance of older high-performance computing equipment where ECL interfaces remain necessary for signal integrity.
Replacement Considerations
Check for direct equivalents from Texas Instruments which acquired National Semiconductor. Verify pin-to-pin compatibility with other dual ECL flip-flops. Ensure logical function remains identical for seamless integration.
