It delivers 150 Mbps per channel with unidirectional data flow, arranged as two channels on side 1 and two on side 2. The 3000 Vrms isolation rating covers basic insulation for industrial and medical equipment where galvanic separation of signal grounds is required. ## 75 kV/µs CMTI — why it matters for motor drives Common-mode transient immunity is rated at 75 kV/µs minimum. In a variable-frequency drive or inverter stage, the fast switching edges on the high-side gate driver can inject several kV/µs across the isolation barrier. A CMTI below that threshold risks data corruption or latch-up. This part's 75 kV/µs rating gives margin for most 600 V / 1200 V IGBT switching events. ## Propagation delay and pulse-width distortion Maximum propagation delay is 13 ns in both directions, with pulse-width distortion held to 3 ns. Rise and fall times are 2.5 ns typical. For a 150 Mbps link (6.67 ns bit period), the 13 ns delay means the isolator adds roughly two bit-clock cycles of latency — fine for SPI clock rates up to 50 MHz, but worth budgeting in a closed-loop control path. ## Package and footprint Housed in a 16-pin SOIC with 3.90 mm body width (0.154 inch), the ADUM142E1BRZ uses a standard narrow SOIC footprint. No external isolated power supply is needed — the part draws its bias from the logic-side rails on each side. ## Lifecycle and supply posture ADI lists this part as Active.","metaTitle":"ADUM142E1BRZ iCoupler Digital Isolator, 150Mbps, 3000Vrms","metaDescription":"ADUM142E1BRZ 4-channel digital isolator with 150Mbps data rate, 3000Vrms isolation, -40°C to 125°C.
