Product details

100 Mbps capacitive isolator — signal-integrity budget for isolated links

The Texas Instruments ISO7762DBQ is a six-channel, unidirectional digital isolator using capacitive coupling technology, rated for 100 Mbps data rate with 3000 Vrms isolation. The 16 ns max propagation delay (tpLH / tpHL) and 4.9 ns max pulse-width distortion keep the signal-integrity budget tight enough for 100 Mbps NRZ data without needing a retimer.

85 kV/µs CMTI — common-mode transient immunity for motor-drive and inverter apps

With a minimum common-mode transient immunity of 85 kV/µs, the ISO7762DBQ handles the fast voltage slewing found in SiC and GaN gate-drive circuits, motor-drive inverter nodes, and industrial power supplies. The 1.1 ns / 1.4 ns typical rise/fall times contribute to low edge-rate jitter, but the real margin is in the CMTI: a 100 V/ns common-mode step (common in hard-switched converters) is well below the 85 kV/µs floor, so the output stays clean.

Frequently asked questions

What is the difference between ISO7762DBQ and ISO7762FDWQ?

Both are six-channel capacitive isolators in the ISO776x family with identical data rate (100 Mbps), isolation (3000 Vrms), and temperature range (-55°C to 125°C). The difference is the package: the DBQ suffix indicates a 16-SSOP (3.90 mm width) body, while the FDWQ suffix is a 16-SOIC (7.50 mm width) wide-body package. The wider SOIC provides greater creepage distance for higher working-voltage applications. Pin functions are the same, so a layout change is needed only for the footprint.
