RESET/RESET: RESET OUTPUTS
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
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.
SCL: SERIAL CLOCK
A0, A1, A2: DEVICE ADDRESS INPUTs
addressed on a single bus system (refer to Device
Addressing). When the pins are left unconnected, the default
values are zeros.
These are open drain pins and RESET can be used as a
The bidirectional serial data/address pin is used to transfer
Serial clock input.
When hardwired, up to eight CAT1640/41 devices may be
