FUNCTION

Chip-Select Input. Drive low to change wiper position (W) through INC and U/D. A low-to-

high transition with INC high stores the wiper position in nonvolatile memory.

Ground

Up/Down Control Input. With U/D low, a high-to-low INC transition decrements the wiper

position. With U/D high, a high-to-low INC transition increments the wiper position.

Wiper Increment Control Input. With CS low, the wiper position moves in the direction

determined by the state of U/D on a high-to-low transition.

High Terminal of Resistor. The voltage at H can be greater than or less than the voltage at L.

Current can flow into or out of H.

Power Supply

Wiper Terminal of Resistor

Low Terminal of Resistor. The voltage at L can be greater than or less than the voltage at H.

Current can flow into or out of L.
