150 Mbps, 3750 Vrms — signal integrity and safety margin
The ADUM142E1BRWZ-RL is a 4-channel, unidirectional digital isolator from Analog Devices' iCoupler series, built on magnetic coupling technology. It delivers a 150 Mbps data rate with 2.5 ns typical rise/fall times and a maximum propagation delay of 13 ns each way, keeping timing closure tight for SPI, UART, or parallel bus isolation. The 3750 Vrms isolation rating provides reinforced insulation for medical, industrial, and grid-tied designs where safety certification matters. Common-mode transient immunity is rated at a minimum 75 kV/µs, so fast-switching edges from motor drives or inverters won't glitch the data stream.
The 2/2 input-to-output split (two channels each way) suits half-duplex interfaces like RS-485 or CAN where the direction control is shared.
For designs requiring a second source, the pin-compatible ADUM142E0BRWZ is a functional alternative within the same iCoupler family — verify the data rate and isolation specs against your system requirements.
