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.

1
PU The PU is a falling-edge triggered input with internal pull-up. Toggling PU will move the wiper close to RH
terminal.

2
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.

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
