Logic Output Optoisolators datasheet and documents for FOD0721

FOD0721

Logic Output Optoisolators Overview

The onsemi FOD0721 is a high-speed logic gate optocoupler featuring a single channel with push-pull output. It utilizes an AlGaAs LED coupled to a CMOS detector IC for signal transmission. Key electrical parameters include a data rate of 25 Mbps, isolation voltage of 3750 Vrms, and common-mode transient immunity (CMTI) of 20 kV/µs. The device operates within a supply voltage range of 4.5V to 5.5V, supports a forward current of 10 mA, and delivers an output current of 10 mA. Typical rise and fall times are 5 ns and 4.5 ns respectively, with maximum propagation delays of 40 ns. Operating temperature ranges from -40°C to +100°C.

Logic Output Optoisolators Feature Summary

Logic Output Optoisolators Procurement Notes

Verify the specific suffix (e.g., R2 for tape and reel) against the required packaging format. Confirm RoHS compliance status and material declaration requirements for your region. Ensure the SOIC-8 package dimensions match your PCB footprint constraints. Check lead time availability as standard delivery periods may vary by distributor.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The 25 Mbps data rate suits applications needing rapid signal transfer. Consider the 3750 Vrms isolation rating for safety-critical circuits. Evaluate the 20 kV/µs CMTI to ensure stability in electrically noisy environments compared to slower alternatives.
