are equivalent to the fixed terminals of a mechanical

V

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

Ω to

400

Up/Down (U/D)

The U/D input controls the direction of the wiper movement

and whether the counter is incremented (up) or decremented

(down).

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. The

current counter value is stored in nonvolatile memory when

CS is returned HIGH while the INC input is also HIGH. After

the store operation is complete the X9116 will be placed in

the low power standby mode until the device is selected

once again.

Principles of Operation

There are three sections of the X9116: the input control,

counter and decode section; the nonvolatile memory; and
