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.

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.
