PIN DESCRIPTIONS
V
The high (V
equivalent to the fixed terminals of a mechanical
potentiometer. The minimum voltage is –5V and the
maximum is +5V. It should be noted that the terminol-
ogy of V
L
and V
H
references the relative position of the
terminal in relation to wiper movement direction
selected by the U/D input and not the voltage potential
on the terminal.

the wiper within the array is determined by the control
inputs. The wiper terminal series resistance is typically

Up/Down (U/D)
The U/D input controls the direction of the wiper move-
ment and whether the counter is incriminated or decre-
mented.
Increment (INC)
The
INC

the counter in the direction indicated by the logic level
on the U/D input.
input is negative-edge triggered. Toggling INC
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 device
will be placed in the low power standby mode until the
device is selected once again.
