PIN DESCRIPTIONS
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.
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 R
H
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
R
L
terminal.
R
H:
High End Potentiometer Terminal
R
H
is the high end terminal of the potentiometer. It is not
required that this terminal be connected to a potential
greater than the R
L
terminal. Voltage applied to the R
H
terminal cannot exceed the supply voltage, V
CC
or go
below ground, GND.
R
W
: Wiper Potentiometer Terminal
R
W
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 R
W
terminal cannot
exceed the supply voltage, V
CC
or go below ground, GND.
R
L
: Low End Potentiometer Terminal
R
L
is the low end terminal of the potentiometer. It is not
required that this terminal be connected to a potential
less than the R
H
terminal. Voltage applied to the R
L
terminal cannot exceed the supply voltage, V
CC
or go
below ground, GND. R
L
and R
H
are electrically
interchangeable.

: Chip Select
The chip select input is used to activate the control input
of the CAT5116 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.
