Logic Output Optoisolators Procurement Notes

Verify the specific ordering suffix matches the required tape-and-reel configuration for surface-mount processing. Confirm that the 5000 Vrms isolation rating aligns with safety regulatory requirements for the target application environment. Ensure the open-collector output type is compatible with the downstream logic circuitry pull-up resistor specifications. Validate component authenticity through authorized distribution channels to guarantee datasheet parameter compliance.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is necessary within a compact surface-mount footprint. The 10 Mb/s data rate suits moderate-speed digital signaling where propagation delay consistency is critical. Consider the open-collector output topology for flexible voltage level interfacing via external pull-up resistors. Evaluate the 15 kV/µs CMTI rating against potential noise environments to ensure reliable signal integrity during fast switching events.
