H11L2TM

Logic Output Optoisolators Overview

The onsemi H11L2TM is a single-channel logic output optocoupler housed in a 6-DIP package. It integrates an AlGaAs infrared LED with an open-collector Schmitt trigger output, providing noise immunity and clean signal transitions. The device offers a typical propagation delay of 4µs and supports data rates up to 1MHz. Key electrical parameters include a maximum forward current of 30mA, a typical forward voltage of 1.2V, and a high isolation voltage of 4170Vrms. It operates within a temperature range of -40°C to 85°C.

Logic Output Optoisolators Feature Summary

• Integrates a Schmitt trigger at the output stage to eliminate noise-induced false triggering and ensure stable digital logic levels.
• Features an open-collector output configuration compatible with various logic families for flexible interface design.
• Utilizes an AlGaAs LED source to achieve high common-mode transient immunity and reliable optical coupling.

Logic Output Optoisolators Applications

• Signal isolation in microprocessor-based control systems
• Noise filtering in industrial communication interfaces
• Logic level translation between different voltage domains

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'TM' against the manufacturer's latest datasheet to confirm pinout and packaging dimensions, as suffixes often denote tape-and-reel or bulk variations. Ensure the procurement channel provides original manufacturer documentation to validate RoHS compliance and UL certification status prior to integration into safety-critical designs.

Logic Output Optoisolators Selection Notes

Select this component when high noise immunity is required due to its integrated Schmitt trigger output, which prevents oscillation from slow input signals. It is suitable for applications requiring moderate speed (up to 1MHz) and robust galvanic isolation. Compare the 4170Vrms isolation rating against system requirements and consider the 6-DIP package constraints for PCB layout space.

Logic Output Optoisolators Part Context

This part belongs to the H11L series of logic output optocouplers from onsemi. The series is designed for general-purpose digital isolation, offering a balance of speed and reliability. The H11L2 variant specifically features the Schmitt trigger output, distinguishing it from standard transistor-output variants like the H11L1.

Logic Output Optoisolators Replacement Considerations

Compatible substitutes include the H11L2TVM (bulk DIP) and H11L2SR2M (surface mount PDIP). Verify that replacement parts maintain the same 4170Vrms isolation rating and Schmitt trigger functionality to ensure circuit compatibility without redesign.
