LA6393DLL-E

Overview

The LA6393DLL-E is a high-performance dual comparator manufactured by onsemi. It operates from a single power supply voltage over a wide range of 2.0 V to 36.0 V, or dual supplies of ±1.0 V to ±18.0 V. The device features a wide common-mode input voltage range extending from 0 V to VCC–1.5 V and utilizes open-collector outputs that enable wired OR configurations. Designed for low power consumption, it exhibits a small current drain of 0.6 mA. The component is housed in an 8-pin DIP package, facilitating compact assembly in multisignal parallel comparator circuits requiring high density.

Feature Summary

• Wide operating power-supply voltage range supporting single and dual supply configurations
• Open-collector output architecture enabling flexible wired OR logic connections
• Low power consumption with minimal current drain suitable for energy-efficient designs

Applications

• Multisignal parallel comparator circuits
• High-density assembly applications
• General-purpose signal comparison tasks

Procurement Notes

Verify the manufacturer designation carefully, as the LA6393D part number has been produced by multiple vendors including Sanyo Semicon Device and STMicroelectronics. Confirm that the specific suffix DLL-E corresponds to the intended pinout and electrical specifications required for your design. Ensure compatibility with existing board layouts before finalizing procurement decisions.

Selection Notes

Select this component when a dual comparator with wide supply voltage flexibility and low static power consumption is required. The open-collector output allows for easy interfacing with various logic families through external pull-up resistors. Consider the DIP-8 package constraints if space is limited, as surface mount alternatives may exist within the same family but require different footprint planning.

Part Context

This device belongs to a series of high-performance dual comparators designed for versatile analog signal processing. The technology emphasizes low power operation alongside robust input characteristics, making it suitable for battery-powered or thermally constrained environments. The dual configuration reduces bill of materials compared to using discrete single comparators.

Replacement Considerations

Check datasheets for other manufacturers offering similar dual comparators with open-collector outputs. Verify that replacement parts maintain the same supply voltage range and input common-mode specifications to ensure circuit functionality without modification.
