CS

¯¯¯

Chip-Select Input. A high-to-low CS

¯¯¯ transition determines the mode: increment if U/D

¯ is high, or

decrement if U/D

¯ is low. CS

¯¯¯ is also used for one-time programming (see the One-Time

Programming section).

Up/Down Control Input. With CS

¯¯¯ low, a low-to-high transition increments or decrements the

wiper position.

Notes:

(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this

specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
