It delivers a 100Mbps data rate across all channels while maintaining 5000Vrms isolation and a minimum common-mode transient immunity of 85kV/µs — parameters that matter when isolating SPI, UART, or parallel data buses in motor drives, battery management, and on-board chargers. ## 85 kV/µs CMTI — what it means for motor-drive and inverter designs Common-mode transient immunity (CMTI) of 85kV/µs is the figure that determines whether the isolator maintains data integrity when high-voltage switching transients slam across the isolation barrier. In a 48V or 400V traction inverter, the switching node can slew at tens of kV/µs; a CMTI rating below that threshold risks bit errors or latch-up. The ISO7761QDWQ1's 85kV/µs minimum provides margin for most automotive and industrial motor drives, including SiC and GaN based designs where edge rates are fastest. The propagation delay is a symmetrical 16ns max for both tpLH and tpHL, with pulse-width distortion held to 4.9ns max — tight enough for high-speed PWM signalling without excessive timing skew. ## Wide supply range and flexible channel configuration The supply voltage range spans 2.25V to 5.5V on both sides, allowing direct interface with 2.5V, 3.3V, and 5V logic families without external level shifters. The six channels are configured with five inputs on side 1 and one input on side 2 — a split that suits applications like isolating a 4-bit or 8-bit parallel bus plus a single control signal, or five sensor inputs and one enable/status line. The unidirectional channel type means each channel's direction is fixed; there is no bidirectional or configurable I/O. The 16-SOIC wide-body package (7.50mm width) provides the creepage distance needed for the 5000Vrms isolation rating.","metaTitle":"TI ISO7761QDWQ1 Digital Isolator, 6-Ch, 100Mbps, 5000Vrms","metaDescription":"TI ISO7761QDWQ1 automotive-grade digital isolator: 6 unidirectional channels, 100Mbps data rate, 5000Vrms isolation, 85kV/µs CMTI, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Type":"General Purpose","Grade":"Automotive","Package":"Tube","Data Rate":"100Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Isolated Power":"No","Package / Case":"16-SOIC (0.295\\\", 7.50mm Width)","lifecycle_stage":"eol_hot","Voltage - Supply":"2.25V ~ 5.5V","Number of Channels":"6","Voltage - Isolation":"5000Vrms","Operating Temperature":"-40°C ~ 125°C","Inputs - Side 1/Side 2":"5/1","Rise / Fall Time (Typ)":"1.1ns, 1.4ns","Supplier Device Package":"16-SOIC","Pulse Width Distortion (Max)":"4.9ns","Propagation Delay tpLH / tpHL (Max)":"16ns, 16ns","Common Mode Transient Immunity (Min)":"85kV/µs"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.74","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.74000","currency":"USD"},{"qty":10,"price":"$5.15900","currency":"USD"},{"qty":25,"price":"$4.87680","currency":"USD"},{"qty":100,"price":"$4.22650","currency":"USD"},{"qty":250,"price":"$4.00980","currency":"USD"},{"qty":500,"price":"$3.59798","currency":"USD"},{"qty":1000,"price":"$3.03444","currency":"USD"},{"qty":2500,"price":"$2.88272","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ae78c2e9eccd285c59f5fc0b5d53b3ac.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the ISO7761QDWQ1 and what is the price?","answer":"The ISO7761QDWQ1 is available to order through independent distribution.

The key difference is channel count: the ISO7741QDWRQ1 has four unidirectional channels (3/1 input split) versus six channels (5/1) on the ISO7761QDWQ1. Both parts share the same 100Mbps data rate, 5000Vrms isolation, and 16ns propagation delay, but the ISO7741QDWRQ1 has a lower CMTI of 40kV/µs versus 85kV/µs. If six channels are not needed, the four-channel variant is a direct drop-in for reduced channel count designs."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/ISO7761QDWQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/ISO7761QDWQ1 when reusing this data.
