Active-Low Register A Chip-Select Input. Drive CSA low to change wiper position WA through INCA and UDA.
Register A Up/Down Control Input. With UDA low, a high-to-low transition at INCA decrements the WA posi-
tion towards LA. With UDA high, a high-to-low transition at INCA increments WA position toward HA.
Register B Up/Down Control Input. With UDB low, a high-to-low transition at INCB decrements the WB posi-
tion towards LB. With UDB high, a high-to-low transition at INCB increments WB position toward HB.
Power-Supply Input. Bypass V
Resistor A Wiper Terminal
Resistor A High Terminal. The voltage at HA can be higher or lower than the voltage at LA. Current can flow
into or out of HA.
Resistor A Low Terminal. The voltage at LA can be higher or lower than the voltage at HA. Current can flow
into or out of LA.
Resistor B Low Terminal. The voltage at LB can be higher or lower than the voltage at HB. Current can flow
into or out of LB.
Resistor B High Terminal. The voltage at HB can be higher or lower than the voltage at LB. Current can flow
into or out of HB.
Resistor B Wiper Terminal

Register B Wiper Increment Control Input. With UDB low, a high-to-low transition at INCB decrements the
WB position towards LB. With UDB high, a high-to-low transition at INCB increments WB position toward HB.
