H11L3SR2M

Logic Output Optoisolators Overview

The H11L3SR2M is a single-channel logic output optocoupler from onsemi, featuring an integrated Schmitt trigger for noise immunity. It utilizes a surface-mount SMD-6 package and provides 4170 Vrms isolation voltage. The device supports a typical data rate of 1 MBps with rise and fall times of 100 ns. Operating temperatures range from -40°C to +85°C. Key electrical parameters include a maximum forward current of 30 mA, forward voltage of 1.2 V, and continuous output current of 50 mA.

Logic Output Optoisolators Feature Summary

• Integrated Schmitt trigger input eliminates the need for external components and ensures clean signal transitions.
• High common-mode transient immunity (CMTI) prevents latch-up and oscillation across voltage and temperature ranges.
• Microprocessor-compatible drive capability simplifies interface design for digital systems.

Logic Output Optoisolators Applications

• Logic-to-logic isolation in microprocessor systems
• Programmable current level sensing circuits
• Signal transmission between isolated digital domains

Logic Output Optoisolators Procurement Notes

Verify the specific suffix SR2M confirms the tape-and-reel packaging format required for automated assembly processes. Confirm RoHS compliance status matches project environmental regulations. Ensure the 6-SMD footprint aligns with the target PCB layout specifications before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation with built-in noise filtering is required. The Schmitt trigger feature distinguishes it from standard transistor-output optocouplers by providing defined switching thresholds. Consider the 4170 Vrms isolation rating for safety-critical applications requiring robust galvanic separation between circuit sections.

Logic Output Optoisolators Part Context

This part belongs to the H11L series of logic output optocouplers designed for high-speed digital isolation. Unlike the H11F series which uses MOSFET outputs, the H11L series integrates a Schmitt trigger for direct logic interfacing. The 'SR2M' designation typically indicates the specific reel packaging configuration used by onsemi for surface-mount production lines.

Logic Output Optoisolators Replacement Considerations

Direct substitutes within the same family include H11L1SR2M or H11L2SR2M, depending on pinout compatibility requirements. Verify that alternative parts maintain the same 6-SMD package and 4170 Vrms isolation rating to ensure mechanical and electrical interchangeability without redesigning the isolation barrier.

Logic Output Optoisolators FAQ

What is the function of the integrated Schmitt trigger?

The Schmitt trigger converts slow-rising input signals into sharp, well-defined output pulses, eliminating noise-induced false triggering and ensuring reliable logic-level isolation.

Does the H11L3SR2M suffer from latch-up issues?

No, the device is designed to be free from latch-up and oscillation throughout its specified voltage and temperature operating ranges, ensuring stable performance in noisy environments.
