KA319D

Overview

The KA319D is a dual voltage comparator manufactured by onsemi, housed in an 8-pin SOIC surface-mount package. It features open-collector outputs and operates within a supply voltage range of 5V to 30V. The device provides a typical propagation delay of 80ns and supports an output current of 25mA. Designed for commercial applications, it functions reliably across a temperature range of 0°C to 70°C with an input offset voltage of 8mV.

Feature Summary

• Dual channel configuration providing independent comparison capabilities
• Open-collector output structure for flexible interfacing
• High-speed response suitable for rapid signal processing

Applications

• Over-voltage detection circuits
• Window comparator designs
• Logic level translation interfaces

Procurement Notes

Verify the specific manufacturer datasheet for the KA319D to confirm pinout compatibility and electrical limits before integration. Ensure that the selected component meets the required operating temperature range and supply voltage specifications for the target application environment.

Selection Notes

Select this component when a dual comparator solution is required in a compact surface-mount form factor. Consider the open-collector output requirement and ensure external pull-up resistors are included in the design to achieve the desired logic levels.

Part Context

This part belongs to the LM319 family of dual comparators. It shares functional similarities with other industry-standard dual comparator ICs but is distinguished by its specific packaging and manufacturer-defined performance characteristics within the commercial temperature grade.

Replacement Considerations

Cross-reference with LM319DR or similar dual comparator variants from other manufacturers. Verify that substitute parts match the 8-pin SOIC footprint and maintain equivalent electrical parameters such as supply voltage range and propagation delay.
