• Description: Digitally Controlled Potentiometer
• Manufacturer: INTERSIL [Intersil Corporation]

Ordering Information
NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are 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.
*Add “T1” suffix for tape and reel.

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.
Up/Down (U/D). The U/D input controls the direction of the wiper movement and whether the counter is incremented
or decremented.

minimum voltage is V SS and the maximum is V CC . The terminology of R

R
minimum voltage is V SS and the maximum is V CC . The terminology of R
the terminal in relation to wiper movement direction selected by the U/D input.
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.
