The Texas Instruments ISO6762DWR is a six-channel digital isolator using capacitive coupling, rated for 50 Mbps per channel with 5000 Vrms isolation. That 50 Mbps data rate means it handles fast SPI clocks and high-speed RS-485 without adding a timing bottleneck — the 18 ns propagation delay (max) keeps bus turnaround tight, and the 7 ns pulse-width distortion won't eat into your setup-and-hold margin. Six channels with a 4/2 input-side split (four on side 1, two on side 2) cover a typical SPI-plus-control-signal bundle — chip select, clock, MOSI, MISO, plus two enable or fault lines — without needing a second device.
Wide supply range and industrial temperature — design-in flexibility
The 16-SOIC (7.50 mm width) package is a standard footprint; the wide-body version gives the creepage distance needed to maintain the 5000 Vrms isolation rating across the board.
