H11L3TM

Logic Output Optoisolators Overview

The onsemi H11L3TM is a single-channel optocoupler featuring an LED input and an open-collector NPN phototransistor output. It utilizes a 6-DIP package with a 0.400-inch (10.16mm) pin spacing. The device provides an isolation voltage of 4170Vrms and operates within a temperature range of -40°C to 85°C. Key electrical parameters include a maximum DC forward current of 30mA, a typical forward voltage of 1.2V, and a data rate of 1MHz. Propagation delays are specified at 4µs for both low-to-high and high-to-low transitions.

Logic Output Optoisolators Feature Summary

• Provides galvanic isolation between input and output circuits using an open-collector phototransistor configuration.

Logic Output Optoisolators Applications

• General-purpose digital signal isolation in industrial control systems
• Microcontroller interface circuits requiring logic-level isolation
• Power supply feedback loops for voltage regulation

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'TM' against official datasheets to confirm package dimensions and tape-and-reel specifications. Ensure compatibility with existing PCB footprints, as DIP-6 variants may differ in pin pitch. Confirm RoHS compliance status and check for recent Product Change Notifications regarding assembly or material declarations before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when a standard 6-pin DIP form factor is required for through-hole mounting. The 4170Vrms isolation rating suits applications needing robust barrier protection. Consider the 1MHz data rate and 4µs propagation delay for timing-sensitive digital interfaces. Verify that the open-collector output architecture aligns with the pull-up requirements of the receiving circuitry.

Logic Output Optoisolators Part Context

This part belongs to the H11L series of logic-output optocouplers from onsemi. These devices are designed for general-purpose isolation tasks where compact size and reliable performance are necessary. The series typically offers various output configurations and packaging options to accommodate different board layout constraints and isolation voltage requirements.

Logic Output Optoisolators Replacement Considerations

Check for direct substitutes such as the H11L3VM variant, which shares similar electrical characteristics but may differ in packaging or reel specifications. Verify pinout compatibility and isolation ratings before substituting any other manufacturer's equivalent components.
