H11N3

Logic Output Optoisolators Overview

The onsemi H11N3 is a high-speed logic output optocoupler featuring an internal Schmitt trigger. It provides 5 Mb/s data rate capability with propagation delays of 7.5 ns rise and 12 ns fall times. The device offers 5300 Vrms insulation voltage and supports up to 50 mA output current. It operates within a temperature range of -40°C to +85°C and is housed in a PDIP-6 package.

Logic Output Optoisolators Feature Summary

• Integrates a Schmitt trigger input for noise immunity and clean signal transitions
• Provides high-speed digital isolation with fast propagation characteristics
• Features open collector output configuration for flexible interfacing

Logic Output Optoisolators Applications

• High-speed digital communication interfaces requiring galvanic isolation
• Noise-sensitive logic circuits needing Schmitt trigger conditioning
• Industrial control systems utilizing isolated signal transmission

Logic Output Optoisolators Procurement Notes

Verify component authenticity through authorized channels as the H11N3 may be discontinued or superseded by newer variants such as the H11N3M. Confirm datasheet revisions match design requirements. Check RoHS compliance status carefully, as older batches may not meet current environmental standards. Ensure packaging type aligns with assembly processes.

Logic Output Optoisolators Selection Notes

Select this component when Schmitt trigger functionality is required for noise rejection in high-speed isolation applications. Compare against standard logic outputs if noise immunity is not critical. Verify that the 5300 Vrms isolation rating meets system safety requirements. Consider the PDIP-6 package constraints for PCB layout and thermal management during selection.

Logic Output Optoisolators Part Context

The H11N3 belongs to onsemi's H11N series of high-speed optocouplers. This family focuses on providing reliable digital isolation with enhanced noise immunity through integrated Schmitt triggers. It serves as a specialized variant within the broader H11N lineup, distinguished by its specific trigger characteristics compared to standard logic output versions.

Logic Output Optoisolators Replacement Considerations

Direct substitutes include the H11N3M, which shares similar specifications but may differ in packaging or compliance status. Verify pinout compatibility and electrical parameters before substitution. Consult official replacement guides for updated availability and regulatory compliance information.
