It delivers 3000Vrms of galvanic isolation across a 3V to 5.5V supply range, with a 100Mbps data rate that comfortably handles SPI clock lines, UART signals, or general-purpose logic-level isolation in industrial fieldbus, motor-drive feedback, and medical patient-interface circuits. ## Propagation delay and timing margin With a 24ns max propagation delay (tpLH / tpHL) and 2ns pulse-width distortion, the ADUM1285CRZ-RL7 adds a predictable, symmetric delay to the signal path. For a 100Mbps NRZ signal (10ns bit period), the 24ns delay is about 2.4 bit-times — acceptable for most isolation barriers where the downstream logic can tolerate a few clock cycles of latency. The 2.5ns typical rise/fall time keeps the edge rate fast enough that the receiving side sees clean transitions, reducing the chance of metastability in a downstream flip-flop. ## Common-mode transient immunity — the motor-drive spec A minimum 25kV/µs CMTI rating means this part holds its output state when a fast voltage transient slams across the isolation barrier — the kind of event you get from an IGBT switching 600V in a few nanoseconds. If your design has a motor drive, an inverter, or a switched-mode power supply sharing a ground with the isolated side, this is the parameter that keeps the data from glitching. The iCoupler magnetic-coupling architecture inherently handles these edges better than an optocoupler, which tends to couple the transient through the LED-to-phototransistor capacitance. ## Channel count and direction — two out, none back Both channels drive from side 1 to side 2 (2/0 input count). That means you get two forward-direction isolated paths, no reverse channel. For a typical SPI isolation job you'd use one channel for the clock and one for the MOSI data, and then need a separate isolator (or a bidirectional variant) for the MISO return. Designers pairing this with a part like the ADUM1201 (which has one forward and one reverse channel) can cover a full SPI bus in two packages. The 125°C upper limit matches the junction temperature of many motor-drive control boards sitting near the heatsink — no derating worry at the typical 85°C ambient. ## Lifecycle and supply posture ADI lists the ADUM1285CRZ-RL7 as an active product with ROHS3 compliance.","metaTitle":"ADUM1285CRZ-RL7 iCoupler Digital Isolator, 100Mbps, 3000Vrms","metaDescription":"ADUM1285CRZ-RL7 iCoupler digital isolator: 2 channels, 100Mbps data rate, 3000Vrms isolation, -40°C to 125°C.
