It supports a data rate of 150 Mbps with propagation delays of 13 ns max and pulse-width distortion under 3 ns, making it suitable for isolating high-speed digital interfaces like SPI, UART, or CAN. With a common-mode transient immunity of 75 kV/µs, it is designed for noisy industrial environments such as motor drives, inverters, and power supplies where fast voltage transients are common. The 4-channel unidirectional configuration (3 inputs on side 1, 1 on side 2) fits designs needing three downstream signals and one feedback path. ## 150 Mbps data rate and timing margins At 150 Mbps, the ADUM141E1BRWZ handles full-speed SPI clock lines, parallel data buses, and high-speed serial links without adding significant skew. The 13 ns max propagation delay (both directions) and 3 ns max pulse-width distortion mean the isolator introduces less than one clock cycle of latency at 50 MHz, which is tight enough for most control-loop feedback paths. The 2.5 ns typical rise/fall times keep signal integrity clean on short PCB traces, but you should still match trace lengths between channels to avoid skew-induced setup violations. ## 3750 Vrms isolation and 75 kV/µs CMTI The 3750 Vrms isolation rating covers reinforced insulation requirements for industrial equipment per IEC 60747-5-5. The 75 kV/µs common-mode transient immunity is the spec that matters when the isolator sits across a motor-drive phase leg or a switched-mode power supply — fast voltage edges on the high side can couple through parasitic capacitance and corrupt data if the isolator's CMTI is too low. This part's 75 kV/µs minimum ensures reliable data transmission even with 1000 V/ns common-mode slew rates, which is typical for SiC and GaN gate-drive stages. ## Supply flexibility and temperature range This simplifies BOM consolidation when the MCU runs at 3.3 V and the isolated peripheral at 5 V. ## Package and footprint Housed in a 16-pin SOIC with 7.50 mm body width (0.295 inch), the ADUM141E1BRWZ uses a standard wide-body footprint common to many multi-channel isolators. The surface-mount package is compatible with reflow soldering; no exposed pad means thermal management relies on the ambient airflow and PCB copper pour. The wide-body SOIC provides adequate creepage distance for the 3750 Vrms isolation rating in most designs. ## Lifecycle and compliance It is ROHS3 compliant, with no known end-of-life notices.","metaTitle":"ADUM141E1BRWZ iCoupler Digital Isolator, 150Mbps, 3750Vrms","metaDescription":"ADUM141E1BRWZ 4-channel digital isolator, 150Mbps data rate, 3750Vrms isolation, -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 (0.295\\\", 7.50mm 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":"3/1","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":"Is ADUM141E1BRWZ a replacement for ADUM140E1BRWZ?","answer":"The ADUM140E1BRWZ is a 4-channel isolator with all four inputs on side 1 (4/0 configuration) and a 3000 Vrms isolation rating, compared to the ADUM141E1BRWZ's 3/1 channel split and 3750 Vrms isolation.
