DESCRIPTION
1
U/D
Controls the direction of wiper movement and whether the counter is incremented or decremented.
2
V-
Negative supply voltage for the potentiometer wiper control.
3
GND
Ground. Should be connected to a digital ground.
4
CS
Chip Select. The device is selected when the CS input is LOW.
5
NC
No Connect. Pin is to be left unconnected.
6
RH
A fixed terminal for one end of the potentiometer resistor.
7
RW
The wiper terminal which is equivalent to the movable terminal of a potentiometer.
8
RL
A fixed terminal for one end of the potentiometer resistor.
9
VCC
Positive logic supply voltage.
10
INC
Increment input; negative edge triggered.
