NOTE

• For open collector output, the signal may become unstable if the input resistance of the connected device is large and the

device may detect the signal incorrectly. In this case, adding a pull-up resistor as shown below will improve the

phenomenon. Select a pull-up resistor in consideration of the input current of the connected device so that the open

collector output current will not exceed the output permissible load current.
