Dual High-Speed Open-Drain
Digital Optical Isolator
Description
The CPC5002 is a dual high speed optical logic
isolator with open-drain outputs providing 3750V_rms 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.
