The PU is a falling-edge triggered input with internal pull-up. Toggling PU will move the wiper close to RH
terminal.
The PD is a falling-edge triggered input with internal pull-up. Toggling PD will move the wiper close to RL
terminal.
The RH and RL pins of the ISL22511 are equivalent to the fixed terminals of a mechanical potentiometer. The
minimum voltage is V SS and the maximum is V CC . The terminology of RH and RL references the relative
position of the terminal in relation to wiper movement direction selected by the PU/PD input.
Ground
The RW pin is the wiper terminal of the potentiometer which is equivalent to the movable terminal of a
mechanical potentiometer.
The RH and RL pins of the ISL22511 are equivalent to the fixed terminals of a mechanical potentiometer. The
minimum voltage is V SS and the maximum is V CC . The terminology of RH and RL references the relative
position of the terminal in relation to wiper movement direction selected by the PU/PD input.
