WP: Write Protect Input
The WP pin when tied low prevents any write operations
within the device.
SCL: Serial Clock
The CAT5140 serial clock input pin is used to clock all
data transfers into or out of the device.
SDA: Serial Data
The CAT5140 bidirectional serial data pin is used to
transfer data into and out of the device. The SDA pin is an
open drain output and can be wire-Ored with the other open
drain or open collector I/Os.
RH, RL: Resistor End Points
The set of RH and RL pins is equivalent to the terminal
connections on a mechanical potentiometer.
RW: Wiper
The RW pin is equivalent to the wiper terminal of a
mechanical potentiometer and its position is controlled by
the WR register.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
2. The minimum DC input voltage is –0.5 V. During transitions, inputs may undershoot to –2.0 V for periods of less than 20 ns. Maximum DC
voltage on output pins is VCC +0.5 V, which may overshoot to VCC +2.0 V for periods of less than 20 ns.
