The part delivers 3000 Vrms isolation with a minimum common-mode transient immunity of 85 kV/µs, which keeps data integrity in noisy inverter environments. The 4/2 input-to-output channel split matches the typical CAN controller side (four inputs) to the transceiver side (two outputs), with the remaining channels available for status or enable signals. The 100 Mbps data rate supports CAN FD (flexible data-rate) frames at the full arbitration and data phase speeds, so this isolator does not become the bottleneck in a high-throughput CAN FD network. The 16 ns maximum propagation delay in both directions keeps the loop delay well within the CAN bit-timing budget, even when accounting for the transceiver and connector delays. Pulse-width distortion is held to 4.9 ns max, which preserves the duty cycle of the CAN signal through the isolation barrier — important for accurate sampling at the receiver. The 1.1 ns typical rise and 1.4 ns fall times are fast enough for 100 Mbps signaling but not so aggressive that they cause excessive ringing on a well-terminated bus. ## Supply range and logic-level compatibility The unidirectional channel architecture is intentional for CAN isolation: the controller-side inputs (Side 1) drive the isolator outputs (Side 2) toward the transceiver, and the transceiver-side outputs (Side 2) feed back to the controller inputs (Side 1) — the 4/2 split matches this exactly. No internal DC-DC converter is included, so an isolated power module or separate supply rail is needed for the secondary side. ## Package and reflow considerations Surface-mount with a pitch that is well within the capability of any modern pick-and-place line. The supplier device package is 16-SSOP, so the same footprint works across the ISO7762 family. Check the MSL rating on the reel label before reflow; if it is MSL 3 or higher and the moisture-barrier bag has been open past the floor-life window, a bake is needed before the oven. ## Lifecycle and sourcing posture For dual-sourcing resilience, the base product number ISO7762 covers multiple channel-count and direction variants — the FQDBQQ1 suffix denotes the 6-channel unidirectional configuration in the 16-SSOP package with automotive qualification.","metaTitle":"TI ISO7762FQDBQQ1 CAN Isolator, 100 Mbps, AEC-Q100, 16-SSOP","metaDescription":"TI ISO7762FQDBQQ1 automotive-grade CAN digital isolator: 6-channel, 100 Mbps, 3000 Vrms isolation, 85 kV/µs CMTI, -40°C to 125°C, 16-SSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Digital Isolators"],"specifications":{"Mfr":"Texas Instruments","Type":"CAN","Series":"Automotive, AEC-Q100","Package":"Tube","Data Rate":"100Mbps","Technology":"Capacitive Coupling","Channel Type":"Unidirectional","Mounting Type":"Surface Mount","Isolated Power":"No","Package / Case":"16-SSOP (0.154\\\", 3.90mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"2.25V ~ 5.5V","Number of Channels":"6","Base Product Number":"ISO7762","Voltage - Isolation":"3000Vrms","Operating Temperature":"-40°C~125°C","Inputs - Side 1/Side 2":"4/2","Rise / Fall Time (Typ)":"1.1ns, 1.4ns","Supplier Device Package":"16-SSOP","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":"$5.2000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ae78c2e9eccd285c59f5fc0b5d53b3ac.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the ISO7762FQDBQQ1 compatible with 5V logic and 3.3V systems?","answer":"Yes.
