Six-channel isolation with 100Mbps throughput
The Texas Instruments ISO7762DWR is a six-channel digital isolator using capacitive coupling technology, delivering 100Mbps data rate per channel with 5000Vrms isolation voltage. The channel direction is fixed at four inputs on Side 1 and two on Side 2, all unidirectional.
The 5000Vrms isolation rating suits equipment requiring reinforced insulation per IEC 60747-17, such as medical patient-contact interfaces, industrial motor drives, and grid-tied power converters. The minimum common-mode transient immunity of 85kV/µs means the isolator holds its output state through fast voltage slew events — critical when the isolation barrier straddles a switching node in a half-bridge or inverter where dV/dt can exceed 50 kV/µs. Propagation delay is symmetric at 16 ns max for both rising and falling edges, with pulse-width distortion held to 4.9 ns max, keeping the duty cycle intact for high-speed serial links like SPI or CAN FD.
The supply range spans 2.25V to 5.5V on both sides, so the same part can bridge a 3.3V MCU domain to a 5V peripheral bus without a level shifter. The wide-body SOIC-16 package provides 8 mm creepage distance between input and output, meeting the clearance requirements of many 5000Vrms-rated designs.
