DESCRIPTION
new system values without effecting the stored
setting. Wiper-control of the CAT5114 is
accomplished with three input control pins, CS, U/D,
and INC. The INC input increments the wiper in the
direction which is determined by the logic state of
the U/D input. The CS input is used to select the
device and also store the wiper position prior to
power down.
The CAT5114 is a single digitally programmable
potentiometer (DPP™) designed as a electronic
replacement for mechanical potentiometers and trim
pots. Ideal for automated adjustments on high volume
production lines, they are also well suited for
applications where equipment requiring periodic
adjustment is either difficult to access or located in a
hazardous or remote environment.
The digitally programmable potentiometer can be
used as a three-terminal resistive divider or as a
two-terminalvariableresistor.DPPsbringvariabilityand
programmability to a wide variety of applications
including control, parameter adjustments, and
signal processing.
The CAT5114 contains a 32-tap series resistor array
connected between two terminals RH and RL. An up/
down counter and decoder that are controlled by three
input pins, determines which tap is connected to the
wiper, RW. The wiper setting, stored in nonvolatile
memory, is not lost when the device is powered
down and is automatically reinstated when power
is returned. The wiper can be adjusted to test

PIN DESCRIPTIONS
RW: Wiper Potentiometer Terminal
INC: Increment Control Input
RW is the wiper terminal of the potentiometer. Its position
on the resistor array is controlled by the control inputs,
INC, U/D and CS. Voltage applied to the RW terminal
cannot exceed the supply voltage, VCC or go below
ground, GND.
The INC input moves the wiper in the up or down
direction determined by the condition of the U/D input.
U/D: Up/Down Control 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 RH terminal. When in a low state
and CS is low, any high-to-low transition on INC will
cause the wiper to move one increment towards the
RL terminal.
RL: Low End Potentiometer Terminal
RL is the low end terminal of the potentiometer. It is not
required that this terminal be connected to a potential
less than the RH terminal. Voltage applied to the RL
terminal cannot exceed the supply voltage, VCC or go
below ground, GND. RL and RH are electrically
interchangeable.
RH: High End Potentiometer Terminal
RH is the high end terminal of the potentiometer. It is not
required that this terminal be connected to a potential
greater than the RL terminal. Voltage applied to the RH
terminal cannot exceed the supply voltage, VCC or go
below ground, GND.
CS: Chip Select
The chip select input is used to activate the control input
of the CAT5114 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.

CAT5114
DEVICE OPERATION
The CAT5114 operates like a digitally controlled
potentiometer with RH and RL equivalent to the high
and low terminals and RW equivalent to the mechanical
potentiometer's wiper. There are 32 available tap posi-
tions including the resistor end points, RH and RL. There
are 31 resistor elements connected in series between
the RH and RL terminals. The wiper terminal is
connected to one of the 32 taps and controlled by three
inputs, INC, U/D and CS. These inputs control a five-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.
wiper (depending on the state of the U/D input and five-
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
CAT5114ispowered-down,thelaststoredwipercounter
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 CAT5114 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.
With CS set LOW the CAT5114 is selected and will
respond to the U/D and INC inputs. HIGH to LOW
transitions on INC wil increment or decrement the
