PIN DESCRIPTION
RESET/RESET
These are open-drain pins and RESET can also be used
as a manual reset trigger input. By forcing a reset condition
on the pin the device will initiate and maintain a reset
condition. The RESET pin must be connected through a
pull-down resistor and the RESET pin must be connected
through a pull-up resistor.
SDA:
The bidirectional serial data/address pin is used to trans-
fer all data into and out of the device. The SDA pin is an
open drain output and can be wire-ORed with other open
drain or open collector outputs.

When hardwired, up to eight CAT1320/21 devices may
be addressed on a single bus system (refer to Device
Addressing). When the pins are left unconnected, the
default values are zeros.
