It provides 2500 Vrms of galvanic isolation across the barrier, which is the standard rating for basic isolation in industrial fieldbus interfaces, PLC digital I/O modules, and isolated sensor links where the working voltage stays under 300 Vrms. The 1 Mbps data rate is the ceiling for each channel — adequate for SPI clock lines up to 1 MHz, UART at standard baud rates, or general-purpose GPIO isolation, but not for high-speed protocols like USB or 100 Mbps Ethernet. The 2/2 channel split (two inputs on side 1, two inputs on side 2) gives you two channels in each direction, which suits half-duplex interfaces like RS-485 or CAN where the data and enable signals cross the barrier in opposite directions. ## 25 kV/µs CMTI — the spec that keeps the data clean in noisy environments Common-mode transient immunity is rated at a minimum of 25 kV/µs. This is the figure that determines whether the isolator holds its output state when a fast high-voltage transient slams across the barrier — exactly what happens in a motor drive when an IGBT switches 600 V in tens of nanoseconds. If the CMTI is too low, the output glitches or toggles, which a downstream controller reads as a spurious pulse. At 25 kV/µs this part is comfortable in industrial inverter drives, servo amplifiers, and switched-mode power supply feedback paths where the dV/dt is aggressive. The propagation delay is a maximum 100 ns in either direction, with a 40 ns pulse-width distortion ceiling — tight enough for most 1 Mbps signalling without skew-induced bit errors. ## Temperature range and package — where it physically goes That covers factory-floor cabinets, outdoor telecom shelters with solar heating, and engine-bay-adjacent electronics in off-highway vehicles. It does not reach the full automotive under-hood range (125°C), so if the ambient around the part exceeds 105°C, you need a higher-temperature isolator. The package is a 16-pin wide-body SOIC (7.50 mm body width), which is the standard footprint for 2500 Vrms reinforced isolation in this channel count. The wide-body gives the creepage distance needed to maintain the isolation rating across the PCB — the narrow SOIC-16 would not hold 2500 Vrms reliably.","metaTitle":"ADUM3402ARWZ-RL iCoupler Digital Isolator, 2500Vrms, 1Mbps","metaDescription":"ADI ADUM3402ARWZ-RL quad-channel digital isolator. 2500Vrms isolation, 1Mbps data rate, -40°C to 105°C.
