CAT5126
PIN DESCRIPTION
Pin Name Function
1 R_W Wiper Connection
Chip-Select Input. A high-to-low C¯¯S¯ transition determines the mode: increment if U/D¯ is high, or
2 C¯¯S¯ decrement if U/D¯ is low. C¯¯S¯ is also used for one-time programming (see the One-Time
Programming section).
3 V_DD Power-Supply Voltage
4 GND Ground
5
V_PP
Programming Voltage for One-Time Programming. Connect V_PP to 10V supply when one-time
programming the device. For normal operation, connect to ground or let float.
6
U/D¯
Up/Down Control Input. With C¯¯S¯ low, a low-to-high transition increments or decrements the
wiper position.
7
R_L Low Terminal of Resistor
8
R_H High Terminal of Resistor

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.
