NOTE:

1. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100%

matte tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations).

Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC

J STD-020.

BRIEF DESCRIPTION

11

PU

The PU is a falling-edge triggered input with internal pull-up. Toggling PU will move the wiper close to RH

terminal.

22

PD

The PD is a falling-edge triggered input with internal pull-up. Toggling PD will move the wiper close to RL

terminal.

RH

The RH and RL pins of the ISL22512 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.

RW

The RW pin is the wiper terminal of the potentiometer which is equivalent to the movable terminal of a

mechanical potentiometer.

7

RL

The RH and RL pins of the ISL22512 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.
