H11L3

Logic Output Optoisolators Overview

The H11L3 is a logic output optocoupler from Everlight's H11LX series, featuring a GaAs infrared emitting diode coupled to a high-speed integrated circuit detector. It provides 5000 Vrms isolation in a DIP-6 package. Key electrical parameters include a rise time of 100 ns, fall time of 100 ns, and a data rate of 1 MHz. The device supports a maximum continuous output current of 50 mA with a forward current of 10 mA. Operating temperature ranges from -55°C to +100°C.

Logic Output Optoisolators Feature Summary

• Integrates a Schmitt trigger for noise immunity and clean digital signal transmission
• Provides high voltage isolation between input and output circuits
• Features high-speed response suitable for digital logic applications

Logic Output Optoisolators Applications

• Power supply regulators
• Digital logic inputs
• Microprocessor inputs

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., M-V) against the manufacturer datasheet to confirm pinout compatibility and RoHS status. Ensure the DIP-6 through-hole package matches the PCB footprint. Confirm that the 5000 Vrms isolation rating meets system safety requirements. Check operating temperature limits for environmental suitability.

Logic Output Optoisolators Selection Notes

Select this component when digital isolation with noise rejection is required. The built-in Schmitt trigger distinguishes it from transistor-output alternatives like the 4N26. Verify that the 1 MHz data rate satisfies the application's speed requirements. Ensure the DIP-6 package fits the available board space and assembly process.

Logic Output Optoisolators Part Context

The H11L3 belongs to the H11LX series, which includes variants like the H11L2 and H11L4. These devices share the same physical package and basic isolation characteristics but differ in internal detector circuitry. The H11LX series is designed for general-purpose digital isolation tasks requiring reliable signal transfer across isolated boundaries.

Logic Output Optoisolators Replacement Considerations

The H11L2 is a direct functional substitute within the same series, offering identical packaging and isolation ratings. Verify pin compatibility before substitution.
