100 Mbps, 3000 Vrms — the isolation spec that decides the bus
The Texas Instruments ISO7762DBQR is a 6-channel, unidirectional digital isolator using capacitive coupling, rated for 100 Mbps data rate and 3000 Vrms isolation voltage. It sits in the ISO776x family and comes in a 16-SSOP package. The 4/2 input/output split (four inputs on side 1, two on side 2) handles mixed-direction isolation buses — think SPI plus a couple of GPIO lines crossing a safety barrier.
85 kV/µs CMTI — why it matters for motor drives and inverters
In a motor-drive or inverter environment where fast-switching IGBTs or SiC FETs slam the ground reference, that figure keeps the output from glitching. The 1.1 ns typical rise and 1.4 ns fall times and 16 ns max propagation delay mean the part keeps up with high-speed control loops without adding skew.
Wide supply, full military temperature range
Supply voltage spans 2.25 V to 5.5 V, so the same reel works on a 2.5 V FPGA bank, a 3.3 V MCU, or a 5 V legacy PLC backplane. No isolated power needed on either side — the part draws its bias from the local rails.
TI lists the ISO7762DBQR as Active.
