Pin Name
Description
1
SDA
Serial Data Input/Output Bidirectional Serial Data pin used to transfer data into and out of the CAT5132.
This is an Open-Drain I/O and can be wire OR’d with other Open-Drain (or Open Collector) I/Os.

VCC
Digital Supply Voltage (2.7 V to 5.5 V)
4
A1
Address Select Input to select slave address for I2C bus.
5
A0
Address Select Input to select slave address for I2C bus.
6
RH
High Reference Terminal for the potentiometer
7
RW
Wiper Terminal for the potentiometer
8
RL
Low Reference Terminal for the potentiometer
9
V+
Analog Supply Voltage for the potentiometer (+8.0 V to 16.0 V)
10
SCL
Serial Bus Clock input for the I2C Serial Bus. This clock is used to clock all data transfers into and out of
the CAT5132

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.
4. Latch-up protection is provided for stresses up to 100 mA on address and data pins from 0.3 V to VCC +0.3 V.
