The 20kV/µs common-mode transient immunity (CMTI) means this part holds its output state when a fast voltage transient slams across the isolation gap — a spec that matters in motor-drive or inverter stages where the switching node swings hundreds of volts in nanoseconds. ## Propagation delay and rise/fall timing for bus margin Maximum propagation delay is 40ns in both directions (tpLH and tpHL), with typical rise and fall times of 5ns and 4.5ns respectively — tight enough to keep the timing budget intact for a 25Mbps data stream across one or two daisy-chained isolators. Supply voltage range is 4.5V to 5.5V, so it runs cleanly on a 5V rail; the logic input is compatible with 5V CMOS or TTL levels, and the push-pull output can source or sink 10mA per channel. ## Active production with ROHS3 compliance The FOD0721R2 is listed as Active in production status and is ROHS3 compliant, so it remains a current BOM line without obsolescence risk or RoHS exemption expiry. Packaged in 8-SOIC (3.90mm width) on tape and reel or cut tape — the same footprint as many other onsemi optoisolators, which simplifies PCB layout reuse across a family.","metaTitle":"FOD0721R2 onsemi Optoisolator 25Mbps 3750Vrms 8-SOIC Active","metaDescription":"onsemi FOD0721R2 optoisolator: 25Mbps data rate, 3750Vrms isolation, push-pull output, 8-SOIC.
