Channel 1 propagates a signal from Side A to Side B, while Channel 2 sends a signal from Side B to Side A. It provides galvanic isolation up to 3750Vrms. When the two sides are powered by supplies with different voltages, it also functions as a logic level translator for supply voltages as low as 2.7V or as high as 5.5V. Available in 8-pin DIP and surface mount packages, it functionally replaces two logic buffers and two single-channel optoisolators. Internal bandgap references regulate the LED drive curr...
