FOD260L

Logic Output Optoisolators Overview

The FOD260L is a single-channel, high-speed logic gate optocoupler featuring an AlGaAs LED coupled to an integrated high-speed photo-detector. It supports data rates up to 10 Mbps with propagation delays of 90 ns (max) and rise/fall times of 22 ns/3 ns (typ). The device offers 5 kVrms isolation voltage, 25 kV/µs minimum CMTI, and operates on 3 V to 5.5 V supply. It handles 50 mA max forward current and 50 mA output current across -40°C to 85°C.

Logic Output Optoisolators Feature Summary

• High-speed signal transmission capability supporting 10 Mbps data rates
• Integrated high-speed photo-detector for fast response times
• Robust electrical isolation with 5 kVrms rating and high common-mode transient immunity

Logic Output Optoisolators Applications

• High-speed digital communication interfaces
• Isolated logic signal transmission in industrial systems
• Data acquisition systems requiring galvanic isolation

Logic Output Optoisolators Procurement Notes

Verify the specific package variant required, as the FOD260L family includes both through-hole DIP-8 (FOD260L) and surface-mount SOIC-8 (e.g., FOD260LS) options. Confirm that the selected part matches the intended PCB footprint and mounting style. Ensure the datasheet version aligns with the requested performance specifications for isolation voltage and speed.

Logic Output Optoisolators Selection Notes

Select this component when high-speed logic isolation is critical. The FOD260L provides superior speed compared to standard transistor-output optocouplers. Consider the 5 kVrms isolation barrier for safety compliance. Verify that the 50 mA input current requirement fits within the driving circuit's capabilities and that the 3 V to 5.5 V operating range matches the system logic levels.

Logic Output Optoisolators Part Context

The FOD260L belongs to onsemi’s FOD series of high-speed logic gate optocouplers. This series is designed for applications demanding rapid signal transfer between isolated circuits. The device utilizes advanced AlGaAs LED technology paired with integrated photodetectors to achieve low propagation delay and high CMTI, distinguishing it from slower general-purpose optocouplers.

Logic Output Optoisolators Replacement Considerations

Direct replacements include other FOD260 variants such as FOD260LS (surface mount) or FOD260LSD. Cross-family alternatives like HCPL-2601 may be considered if pinout compatibility allows, though electrical parameters should be verified against the original design requirements.
