Typical Application (continued)

3. Feedback resistor:

–

A 10-kΩ resistor is chosen here to bias the input so the microcontroller GPIO output can initialize the

input and output. The resistor value is important because a resistance too high, say at 1 MΩ, would

cause too much of a voltage drop, causing the output to no longer be able to drive the input. On the other

hand, a resistor too low, such as a 1 Ω, would not bias enough and might cause current to flow into the

microcontroller, possibly damaging the device.
