PIN DESCRIPTIONS

X9015 are equivalent to the fixed terminals of a

relation to wiper movement direction selected by the

U/D input and not the voltage potential on the terminal.

/V

W

movable terminal of a mechanical potentiometer. The

position of the wiper within the array is determined by the

control inputs. The wiper terminal series resistance is

typically 200

Up/Down (U/D)

The U/D input controls the direction of the wiper

movement and whether the tap postion is incremented or

decremented.

Increment (INC)

The INC input is negative-edge triggered. Toggling INC

will move the wiper and either increment or decrement

the counter in the direction indicated by the logic level on

the U/D input.

Chip Select (CS)

The device is selected when the CS input is LOW. When

CS is returned HIGH while the INC input is LOW the

X9015 will be placed in the low power standby mode until

the device is selected once again.
