PIN DESCRIPTIONS
Host Interface Pins
Serial Clock (SCL)
The SCL input is used to clock data into and out of the
X9428.
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
3 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 X9428. A maximum of 8 devices may occupy the
2-wire serial bus.
