The 2/1 input/output configuration (two channels on side 1, one on side 2) suits applications like isolated SPI, UART, or GPIO where one signal needs to return across the barrier. Typical environments include industrial motor drives, power inverters, medical equipment, and isolated sensor interfaces where reinforced isolation and wide temperature range are required. ## 75 kV/µs CMTI — why it matters for motor drives and inverters Common-mode transient immunity is rated at a minimum of 75 kV/µs. In a motor-drive or inverter application, fast-switching IGBTs or SiC FETs can inject several kV/µs of common-mode voltage across the isolation barrier. If the isolator's CMTI is too low, data errors or latch-up can occur. The 75 kV/µs rating here provides a comfortable margin for most industrial drive designs, even with SiC switching edges. ## Propagation delay and timing margin Maximum propagation delay is 13 ns in both directions (tpLH and tpHL), with a pulse-width distortion max of 3 ns and typical rise/fall times of 2.5 ns. For a 150 Mbps signal (6.67 ns bit period), the 13 ns delay means this isolator is not suitable for clocking data at the full rate in a loopback path — it is best used for control signals, SPI clock and data lines at lower speeds, or UART where the bit period is much longer. The tight 3 ns PWD keeps duty-cycle distortion low for PWM signals. ## Package and supply flexibility No isolated power is generated internally — the part requires separate isolated supplies on each side, which is typical for this class of digital isolator. ## Lifecycle and compliance It is ROHS3 compliant. For designs requiring a second source, the ADUM230E1BRIZ is a pin-compatible 3-channel unidirectional isolator with the same 150 Mbps data rate, 5000 Vrms isolation, and 75 kV/µs CMTI, but with a 3/0 input/output configuration (all three channels on side 1). If your application needs the reverse channel (2/1), the ADUM231D0BRIZ is the correct choice.","metaTitle":"ADUM231D0BRIZ 3-Ch Digital Isolator, 150 Mbps, 5000 Vrms","metaDescription":"ADI ADUM231D0BRIZ iCoupler 3-channel unidirectional digital isolator. 150 Mbps data rate, 5000 Vrms isolation, 1.7-5.5 V supply, -40 to 125°C.
