The CPC5002 is a dual high speed optical logic isolator with open-drain outputs providing 3750Vrms of galvanic isolation between the inputs and the outputs. Activating the input LED causes the open-drain output to turn on, pulling the voltage of the external pullup resistor towards ground. Utilizing CMOS technology enables the output stage's high-gain circuitry to operate with a miserly power consumption of <5mW (typical) when operated with a 3.3V supply voltage and a low input LED drive current of 1.5mA.

Because optical isolators pass logic levels directly there is no internal state refresh clock to maintain a non-changing input. Additionally, the CPC5002 will always return the buffered signals to their proper value after a transient interruption at either side.
