PIN DESCRIPTION
RESET/
RESET
RESET:
RESET OUTPUTS
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:
SERIAL DATA ADDRESS
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.

DEVICE ADDRESS INPUTS
When hardwired, up to eight CAT1640/41 devices may
be addressed on a single bus system (refer to Device
Addressing). When the pins are left unconnected, the
default values are zeros.
