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 k =resistance. The
UC and DC inputs are internally debounced and require no external components for input signal
conditioning.
