It delivers a 150 Mbps data rate with a propagation delay of 13 ns max (both directions) and pulse-width distortion held to 3 ns max. The 2.5 ns typical rise/fall time keeps the eye open for high-speed SPI, UART, or parallel bus isolation. The 75 kV/µs common-mode transient immunity rating means the part rejects fast dV/dt edges from motor drives, inverter stages, or switching supplies without corrupting the data stream — a critical spec when the isolation barrier sees several hundred volts switching at tens of kHz. ## 3750 Vrms isolation — what it covers and what it does not Rated at 3750 Vrms for one minute per the basic isolation spec, this part suits reinforced insulation in mains-connected industrial equipment, medical patient-interface circuits, and motor-drive feedback paths. Note that the part does not include an integrated DC-DC converter for isolated power; the secondary side needs its own supply rail. ## Four unidirectional channels — all inputs on side 1 Channel configuration is 4 inputs on side 1, 0 inputs on side 2 (4/0), meaning all four channels pass data from the primary to the secondary side. This is a fixed-direction part — no bidirectional or configurable channels. For designs needing mixed-direction isolation (e.g., SPI with MISO returning), pair this with a single-channel reverse-direction isolator or use the ADUM140D0BRZ (0/4) for the return path. ## Package and temperature grade Standard SOIC-16 footprint.","metaTitle":"ADUM140D1BRZ Digital Isolator, 150Mbps, 3750Vrms, 4-Channel","metaDescription":"ADUM140D1BRZ 4-channel digital isolator, 150Mbps data rate, 3750Vrms isolation, 75kV/µs CMTI, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"iCoupler®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Series":"iCoupler®","Package":"Tube","Data Rate":"150Mbps","Technology":"Magnetic Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"1.7V ~ 5.5V","Number of Channels":"4","Voltage - Isolation":"3750Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"4/0","Rise / Fall Time (Typ)":"2.5ns, 2.5ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"3ns","Propagation Delay tpLH / tpHL (Max)":"13ns, 13ns","Common Mode Transient Immunity (Min)":"75kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.23","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$4.23000","currency":"USD"},{"qty":10,"price":"$3.79800","currency":"USD"},{"qty":25,"price":"$3.59040","currency":"USD"},{"qty":100,"price":"$3.11180","currency":"USD"},{"qty":250,"price":"$2.95224","currency":"USD"},{"qty":500,"price":"$2.64902","currency":"USD"},{"qty":1000,"price":"$2.23412","currency":"USD"},{"qty":2500,"price":"$2.12242","currency":"USD"}]},"links":{"datasheetUrl":"https://www.analog.com/media/en/technical-documentation/data-sheets/ADuM140D_140E_141D_141E_142D_142E.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between ADUM140D1BRZ and ADUM140D0BRZ?","answer":"The ADUM140D1BRZ has all four channels oriented from side 1 to side 2 (4/0 input count). The ADUM140D0BRZ is the opposite — all four channels from side 2 to side 1 (0/4).

At 1.8 V the 150 Mbps data rate is still supported, though the input thresholds scale with VDD — confirm the logic-family output levels meet the VIH/VIL specs at the chosen supply."},{"question":"What is the tape-and-reel ordering code for ADUM140D1BRZ?","answer":"The tape-and-reel variant is ADUM140D1BRZ-RL7.
