Pin Descriptions
Host Interface Pins
SERIAL CLOCK (SCL)
The SCL input is used to clock data into and out of the
X9408.
SERIAL DATA (SDA)
SDA is a bidirectional pin used to transfer data into and out
of the device. It is an open drain output and may be wire-
ORed with any number of open drain or open collector
outputs. An open drain output requires the use of a pull-up
resistor. For selecting typical values, refer to the guidelines
for calculating typical values on the bus pull-up resistors
graph.
DEVICE ADDRESS (A
The address inputs are used to set the least significant 4 bits
of the 8-bit slave address. A match in the slave address
serial data stream must be made with the address input in
order to initiate communication with the X9408. A maximum
of 16 devices may occupy the 2-wire serial bus.
Potentiometer Pins
V
The V
connections on either end of a mechanical potentiometer.
V
The wiper outputs are equivalent to the wiper output of a
mechanical potentiometer.
