The 100 Mbps data rate covers most industrial fieldbus and sensor interfaces without timing margin issues; propagation delay is 24 ns max per channel, with pulse-width distortion held to 2 ns. The 3000 Vrms isolation rating is tested per basic insulation requirements for equipment rated up to 300 Vrms working voltage in overvoltage category II. Common-mode transient immunity is specified at 25 kV/µs minimum, which keeps the output clean during motor-drive switching or relay contact bounce.","metaTitle":"ADUM1281CRZ-RL7 Digital Isolator, 100 Mbps, 3000 Vrms","metaDescription":"ADUM1281CRZ-RL7 iCoupler digital isolator: 100 Mbps data rate, 3000 Vrms isolation, 2 unidirectional channels, -40 to 125°C, 8-SOIC.
