H11L3G

Logic Output Optoisolators Overview

The H11L3G is a logic output optoisolator from the H11L1 series by Isocom Components. It features a single channel with an open collector output and a Schmitt trigger input for noise immunity. The device provides 5300Vrms isolation voltage and supports data rates up to 1MHz. It operates within a temperature range of -40°C to 85°C and is housed in a 6-pin DIP package.

Logic Output Optoisolators Feature Summary

• Schmitt trigger input configuration enhances noise immunity for digital signal integrity
• Open collector output design allows flexible interfacing with various logic families
• High isolation voltage rating ensures robust electrical separation between circuits

Logic Output Optoisolators Applications

• Microprocessor system interface isolation
• Logic level translation between different voltage domains
• Signal coupling in noisy industrial environments

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'G' corresponds to the lead-free and RoHS compliant version as indicated in manufacturer documentation. Confirm the package type matches the required board layout, as variations exist between through-hole DIP and surface mount options within the broader H11L1 family. Ensure the selected variant meets the specific isolation voltage requirements of the target application circuit.

Logic Output Optoisolators Selection Notes

Select this component when high noise immunity is critical due to its integrated Schmitt trigger input. The open collector output requires appropriate pull-up resistor selection based on the load voltage. Consider the 1MHz speed limit for high-frequency applications and verify that the 5300Vrms isolation rating exceeds the system's safety requirements.

Logic Output Optoisolators Part Context

The H11L3G belongs to the H11L1 series of microprocessor-compatible optocouplers. This series includes variants like H11L1, H11L2, and H11L4, which differ primarily in output configurations such as open collector or push-pull. The H11L3G specifically utilizes a Schmitt trigger input to improve performance in electrically noisy environments compared to standard logic inputs.

Logic Output Optoisolators Replacement Considerations

Compatible substitutes include other H11L1 series devices from Isocom or equivalent parts from manufacturers offering Schmitt-trigger input optocouplers with similar isolation ratings and DIP-6 packaging. Verify pinout compatibility and electrical specifications before substitution.
