The CAT5114 operates like a digitally controlled
potentiometer with R
and low terminals and R
potentiometer's wiper. There are 32 available tap posi-
tions including the resistor end points, R
are 31 resistor elements connected in series between
the R
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.
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

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
CAT5114 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 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.
