H11L3M

Logic Output Optoisolators Overview

The onsemi H11L3M is a single-channel logic output optocoupler featuring a Schmitt trigger output stage. It provides high data rates with a typical speed of 1 MHz (NRZ). The device offers an isolation voltage of 4170 Vrms and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a maximum forward current of 30 mA, a typical forward voltage of 1.2 V, and a maximum continuous output current of 50 mA. Rise and fall times are typically 100 ns, with propagation delays up to 4 µs.

Logic Output Optoisolators Feature Summary

• Integrates a Schmitt trigger output stage for noise immunity and clean signal transitions
• Provides high-speed data transmission capabilities suitable for digital communication interfaces
• Ensures robust electrical isolation between input and output circuits

Logic Output Optoisolators Applications

• Digital signal isolation in microprocessor systems
• Logic level shifting between different voltage domains
• Noise filtering in industrial control environments

Logic Output Optoisolators Procurement Notes

Verify the specific package variant required, as the H11L3M designation covers both through-hole DIP and surface-mount SMD configurations. Confirm that the selected suffix matches the intended mounting style and reel specifications. Ensure compliance with RoHS and REACH regulations as stated in the official documentation before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when Schmitt trigger action is necessary to eliminate signal bounce or noise-induced false triggering in digital logic circuits. The 1 MHz data rate supports moderate-speed serial communications. Verify that the required isolation voltage meets system safety standards and that the operating temperature range aligns with the application environment constraints.

Logic Output Optoisolators Part Context

This part belongs to the H11L series of logic output optocouplers from onsemi. The series is designed for applications requiring reliable digital signal transfer with built-in noise rejection. The H11L3M specifically denotes the version with Schmitt trigger outputs, distinguishing it from open-collector variants like the H11L1.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include other H11L3 variants from onsemi such as H11L3VM or H11L3SR2M, provided the package type (DIP vs. SMD) matches the design. Cross-brand replacements require verification of pinout compatibility, isolation ratings, and switching speeds.
