DS1869

In dual pushbutton mode, each direction is controlled by the up contact (UC) and down contact (DC)

inputs, respectively. No wait states are required to change wiper direction in dual pushbutton mode. In

dual pushbutton mode, as the wiper position reaches the end of the potentiometer, the direction of wiper

movement will not change. Wiper position will remain at the potentiometers’ end until an opposite

direction input is given.

All contact closure control inputs, UC, DC, and D, are internally pulled-up by a 100 kΩ=resistance. The

UC and DC inputs are internally debounced and require no external components for input signal

conditioning.
