Pin Descriptions
SCL: Serial Clock
data transfers into or out of the device.
SDA: Serial Data
transfer data into and out of the device. The SDA pin is an
open drain output and can be wire−OR’d with the other open
drain or open collector outputs.
A0, A1, A2, A3: Device Address Inputs
multiple devices. A total of sixteen devices can be addressed
on a single bus. A match in the slave address must be made
with the address input in order to initiate communication
with the CAT5419.
The CAT5419 serial clock input pin is used to clock all
The CAT5419 bidirectional serial data pin is used to
These inputs set the device address when addressing
