I/O Electrical Characteristics
The smart camera device is an optocoupler isolated input/output. The input current of the optocoupler device is 5~50ma, with a typical value of 20ma. (It is recommended that the input current is 20ma to achieve the best optocoupler input performance.) The output voltage of the optocoupler device does not exceed 80V. The figure below shows the test circuit for the response time of the optocoupler device.
Test environment: VCC=5V, IC=2mA, RL=100Ω
Response Time (Rise): tr typical value 4us, maximum value 18us
Response Time (Fall): tr typical value 3us, maximum value 18us
