Technical details

The 100Mbps data rate handles SPI, UART, and CAN FD isolation requirements typical in automotive sensor and actuator interfaces. Propagation delay is 16ns max (tpLH / tpHL), with pulse-width distortion held to 4.9ns max — tight enough for timing-sensitive links like isolated SPI clock and data.

Channel configuration and package

The device provides 3 channels on side 1 and 1 channel on side 2, all unidirectional. This 3/1 split suits applications like isolated SPI (SCLK, MOSI, CS from the controller side, MISO returning) or isolated UART (TX, RX plus a control signal). The 16-SOIC wide-body package (0.551" body width, 14.00mm) provides the creepage distance needed for 5700Vrms reinforced isolation in a surface-mount footprint. Rise and fall times are 2.4ns typical, keeping signal edges clean at 100Mbps.
