Description

CLK

Clock Input. Each clock pulse executes the step-up or step-down of the resistance. The direction is determined

by the state of the U/D pin. CLK is a negative-edge trigger. Logic high signal can be higher than VDD, but lower

than 5.5 V.

U/D

Up/Down Selections. Logic 1 selects up and Logic 0 selects down. U can be higher than VDD, but lower than 5.5 V.

Resistor Terminal A. GND ≤ VA ≤ VDD.

GND

Common Ground.

Wiper Terminal W. GND ≤ VW ≤ VDD.

Resistor Terminal B. GND ≤ VB ≤ VDD.

Chip Select. Active Low. Logic high signal can be higher than VDD, but lower than 5.5 V.

VDD

Positive Power Supply, 2.7 V to 5.5 V.
