    Need for PU or PD resistor?





      I know that pull- up or pull-down resistor is used to prevent the digital input from floating. I would like to ask you if I need to add pull down or pull up resistor on my circuit.

      The API code is generated for Microcontroller to return 0 or 1 value to control the demultiplexer. Demux is active low. So, If MCU return the low(0) value then, demux will perform its job. The high (1) signal from MCI would set the demux off.



                        Idle : High

                        the moment of need : Low

                        return to high
