LA6339-E-ON

Overview

The LA6339-E-ON is a high-performance quad comparator manufactured by onsemi, formerly Sanyo Semicon Device. It operates from a single power supply ranging from 2.0V to 36.0V or dual supplies of ±1.0V to ±18.0V. The device features a wide common-mode input voltage range extending from 0V to VCC–1.5V and utilizes open-collector outputs that enable wired OR configurations. Designed for low power consumption, it exhibits small current dissipation, making it suitable for multisignal parallel comparator circuits requiring high-density assembly.

Feature Summary

• Wide supply voltage operation supporting single and dual power sources
• Open-collector output architecture facilitating wired OR logic connections
• Low power consumption characteristics optimized for dense circuit layouts

Applications

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

Procurement Notes

Verify the manufacturer origin as the LA6339 was originally produced by Sanyo Semicon Device before its acquisition by Panasonic. Confirm that the 'E' suffix in the part number denotes specific environmental or reliability grades consistent with onsemi's current product line definitions. Ensure compatibility with legacy designs referencing the original Sanyo datasheets.

Selection Notes

Select this component when designing circuits requiring multiple comparators within a single package to minimize board space. The wide input common-mode range allows direct interfacing with various signal levels without additional conditioning. The open-collector outputs provide flexibility in driving different load types and voltages through external pull-up resistors.

Part Context

This component belongs to the family of analog mixed-signal ICs, specifically comparator circuits. Originally developed by Sanyo Electric Co., Ltd., the product line was integrated into onsemi following corporate acquisitions. The LA6339 represents a standard solution for general-purpose comparison tasks in industrial and consumer electronics where power efficiency and compact form factors are prioritized.

Replacement Considerations

Check for direct pin-compatible alternatives from onsemi or other manufacturers offering quad comparators with similar supply voltage ranges. Verify if updated packages or enhanced performance variants are available under the onsemi portfolio. Ensure any substitute maintains the open-collector output structure and comparable input offset voltage specifications.
