H11L1V

Logic Output Optoisolators Overview

The H11L1V is a single-channel optocoupler from Isocom Components, featuring a GaAs infrared emitting diode coupled to a high-speed open collector Schmitt trigger output. It provides 5000 Vrms isolation voltage and supports data rates up to 1 Mbps. The device operates within a temperature range of -55°C to 100°C, with a maximum forward current of 60 mA and typical rise/fall times of 0.1 μs. It is available in DIP-6 and surface-mount packages.

Logic Output Optoisolators Feature Summary

• Integrates a GaAs infrared LED with a high-speed open collector Schmitt trigger for noise-immune digital signal transmission
• Provides robust electrical isolation rated at 5000 Vrms between input and output circuits
• Features AC input compatibility allowing direct connection to AC power lines without external rectification

Logic Output Optoisolators Applications

• AC mains detection and monitoring circuits
• Microprocessor system interface isolation
• Solid-state relay driver circuits
• Logic level translation in noisy environments

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., SM for surface mount) against your PCB footprint requirements. Confirm that the 5000 Vrms isolation rating meets your safety standards, such as UL or VDE, which are applicable to this variant. Ensure the 60 mA maximum forward current aligns with your drive circuit capabilities. Check RoHS compliance status for environmental regulations.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation with built-in hysteresis is required. The Schmitt trigger output eliminates the need for external pull-up resistors in many logic applications. Consider the operating temperature range of -55°C to 100°C for industrial environments. Compare the 1 Mbps data rate against higher-speed alternatives if signal integrity at greater frequencies is critical.

Logic Output Optoisolators Part Context

The H11L1V belongs to the H11L1 series of logic output optoisolators. It is functionally similar to the standard H11L1 but includes additional VDE certification alongside UL approval. This series is designed for applications requiring reliable isolation between low-voltage logic circuits and higher-voltage AC or DC systems.

Logic Output Optoisolators Replacement Considerations

Publicly confirmed substitute part numbers include H11L1SM and H11AV1SM. Verify pinout compatibility and isolation voltage ratings before substitution. Note that some variants may have different packaging styles or certification approvals.
