FOD260LS

Logic Output Optoisolators Overview

The onsemi FOD260LS is a high-speed logic output optocoupler featuring an 8-SMD surface-mount package. It provides electrical isolation with a maximum isolation voltage of 5000Vrms and supports data rates up to 10Mbps. The device includes Schottky-clamped open-collector outputs for enhanced noise immunity and fast switching. Key electrical parameters include a typical rise time of 22ns, a typical fall time of 3ns, and a maximum propagation delay of 90ns. It operates within a supply voltage range of 3V to 5.5V and withstands common-mode transients of at least 25kV/µs.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'LS' against the manufacturer's official datasheet to confirm the exact pinout, tape-and-reel specifications, and moisture sensitivity level. Ensure the selected variant matches the required surface-mount footprint and thermal performance characteristics for the target application environment.

Logic Output Optoisolators Selection Notes

Select this component when high-speed signal integrity and robust noise rejection are critical. The Schottky-clamped output design minimizes ringing and overshoot, making it suitable for sensitive logic circuits. Consider the 8-SMD package constraints and verify that the 5000Vrms isolation rating meets the safety requirements of the system architecture.

Logic Output Optoisolators Part Context

The FOD260LS belongs to onsemi’s FOD series of high-speed optocouplers, designed for demanding applications requiring rapid signal transmission across isolation barriers. This series emphasizes low propagation delay and high common-mode rejection, distinguishing it from standard general-purpose optocouplers used in slower control loops.
