IXYS CPC5001 Series Dual, One Channel Each Direction Digital Optical Isolator

IXYS CPC5001 Series Dual, One Channel Each Direction
Digital Optical Isolator

IXYS CPC5001 Series Dual, One Channel Each Direction Digital Optical Isolatoris is a dual, non-inverting digital optical isolator with buffered-logic inputs and open-drain outputs. 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 currents to 3mA to reduce peak power requirements. Unlike transformer or capacitive isolators, optical isolation passes DC signals, and does not need to be clocked periodically to refresh state. Buffered signals will always return to their proper value
after a transient interruption at either side.
