CAT5126

PIN DESCRIPTION

Pin Name Function

1 RW 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 VDD Power-Supply Voltage

4 GND Ground

5

VPP

Programming Voltage for One-Time Programming. Connect VPP 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

RL Low Terminal of Resistor

RH High Terminal of Resistor

Note:

(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.
