Manufacturer:TI Description:When powered, the DS1668 assumes a single pushbut- ton mode of operation. Pressure applied to the inte- grated pushbutton will cause contact closure which in turn will move the wiper position upward or downward depending on the previous wiper direction. Single push- button mode is accomplished in the same manner for the DS1669. However, for the DS1669, all connections must be made by the user since no internal connections exist (see Figure 1). Note that single pushbutton control is accomplished when 1) the (DC) input is connected to the positive supply input and 2) the (D) input is allowed to float. These two conditions must exist from the time of device powerCup. The UC input controls both upward and downward movement of the device wiper position in single pushbutton mode of operation. |
