BRIEF DESCRIPTION
1PU
The PU is a negative-edge triggered input with internal pull-up. Toggling PU will move the wiper close to RH terminal.
2PD
The PD is a negative-edge triggered input with internal pull-up. Toggling PD will move the wiper close to RL terminal.
3RH
The RH and RL pins of the ISL23512 are equivalent to the fixed terminals of a mechanical potentiometer. The minimum
voltage is Vss and the maximum is Vcc. 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.
4VSS
Ground
6RW
The RW pin is the wiper terminal of the potentiometer, which is equivalent to the movable terminal of a mechanical
potentiometer.
7RL
The RH and RL pins of the ISL23512 are equivalent to the fixed terminals of a mechanical potentiometer. The minimum
voltage is Vss and the maximum is Vcc. 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.
