PIN DESCRIPTIONS
R
The high (R
X9015 are equivalent to the fixed terminals of a
mechanical potentiometer. The minimum voltage is V
and the maximum is V
R
relation to wiper movement direction selected by the
U/D input and not the voltage potential on the terminal.
R
R
movable terminal of a mechanical potentiometer. The
position of the wiper within the array is determined by the
control inputs. The wiper terminal series resistance is
typically 200
position is at tap #15 (V
Up/Down (U/D)
The U/D input controls the direction of the wiper
movement and whether the tap postion is incremented or
decremented.
Increment (INC)
The INC input is negative-edge triggered. Toggling INC
will move the wiper and either increment or decrement
the counter in the direction indicated by the logic level on
the U/D input.
Chip Select (CS)
The device is selected when the CS input is LOW. When
CS is returned HIGH while the INC input is LOW the
X9015 will be placed in the low power standby mode until
the device is selected once again.
