INC: Increment Control Input
The INC input moves the wiper in the up or down direction
determined by the condition of the U/D input.
The U/D input controls the direction of the wiper
movement. When in a high state and CS is low, any high-
to-low transition on INC will cause the wiper to move one
increment toward the R
and CS is low, any high-to-low transition on INC will
cause the wiper to move one increment towards the

of the CAT5113 and is active low. When in a high
state, activity on the INC and U/D inputs will not
affect or change the position of the wiper.
The CAT5113 operates like a digitally controlled
potentiometer with R
and low terminals and R
potentiometer's wiper. There are 100 available tap
positions including the resistor end points, R
There are 99 resistor elements connected in series
between the R
connected to one of the 100 taps and controlled by three
inputs, INC, U/D and CS. These inputs control a seven-
bit up/down counter whose output is decoded to select
the wiper position. The selected wiper position can be
stored in nonvolatile memory using the INC and
CS inputs.
With CS set LOW the CAT5113 is selected and will
respond to the U/D and INC inputs. HIGH to LOW
transitions on INC wil increment or decrement the
wiper (depending on the state of the U/D input and
seven-bit counter). The wiper, when at either fixed
terminal, acts like its mechanical equivalent and does
not move beyond the last position. The value of the
counter is stored in nonvolatile memory whenever CS
transitions HIGH while the INC input is also HIGH. When
the CAT5113 is powered-down, the last stored wiper
counter position is maintained in the nonvolatile memory.
When power is restored, the contents of the memory are
recalled and the counter is set to the value stored.
With INC set low, the CAT5113 may be de-selected
and powered down without storing the current wiper
position in nonvolatile memory. This allows the
system to always power up to a preset value stored
in nonvolatile memory.
