PIN DESCRIPTIONS  
INC: Increment Control Input  
of the CAT5111 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.  
TheINCinput(onthefallingedge)movesthewiperinthe  
up or down direction determined by the condition of the  
U/D input.  
DEVICE OPERATION  
U/D: Up/Down Control Input  
The CAT5111 operates like a digitally controlled  
potentiometer with RH and RL equivalent to the high  
andlowterminalsandRWB equivalentto themechanical  
potentiometer's wiper. There are 100 available tap  
positions including the resistor end points, RH and RL.  
There are 99 resistor elements connected in series  
between the RH and RL terminals. The wiper terminal is  
connectedtooneofthe100 tapsandcontrolledbythree  
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.  
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.  
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.  
With CS set LOW the CAT5111 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  
transitionsHIGHwhiletheINCinputisalsoHIGH. When  
the CAT5111 is powered-down, the last stored wiper  
counterpositionismaintainedinthenonvolatilememory.  
When power is restored, the contents of the memory are  
recalled and the counter is set to the value stored.  
RWB: Wiper Potentiometer Terminal (Buffered)  
RWB is the buffered wiper terminal of the potentiometer. Its  
position on the resistor array is controlled by the control  
inputs, INC, U/D and CS.  
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.  
With INC set low, the CAT5111 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.  
CS: Chip Select  
The chip select input is used to activate the control input
