NOTE: These Intersil Pb-free plastic packaged products employ special Pb-free material sets; molding compounds/die attach materials and 100%
matte tin plate PLUS ANNEAL - e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations.
Intersil Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J
STD-020.

BRIEF DESCRIPTION
INC 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.
U/D Up/Down (U/D). The U/D input controls the direction of the wiper movement and whether the counter is incremented or
decremented.
RH RH. The RH and RL pins of the X93156 are equivalent to the fixed terminals of a mechanical potentiometer. The minimum
voltage is VSS and the maximum is VCC. The terminology of RH and RL references the relative position of the terminal in
relation to wiper movement direction selected by the U/D input.
VSS Ground.
Rw RW. The Rw pin of the X93156 is the wiper terminal of the potentiometer which is equivalent to the movable terminal of a
mechanical potentiometer.
RL RL. The RH and RL pins of the X93156 are equivalent to the fixed terminals of a mechanical potentiometer. The minimum
voltage is VSS and the maximum is VCC. The terminology of RH and RL references the relative position of the terminal in
relation to wiper movement direction selected by the U/D input.
CS Chip Select (CS). The device is selected when the CS input is LOW. The current counter value is stored in nonvolatile
memory when CS is returned HIGH while the INC input is also HIGH. After the store operation is complete, the X93156 will
be placed in the low power standby mode until the device is selected once again.
VCC Supply Voltage.
