PIN DESCRIPTIONS
Host Interface Pins
Serial Clock (SCL)
The SCL input is used to clock data into and out of the
X9448.
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 col-
lector 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 X9448. A maximum of 16 devices may share the
same 2-wire serial bus.
