byte of data. Thus, each byte transferred effectively  
requires 9 bits. The master generates the 9th clock  
pulse, and the recipient pulls down SDA during the  
acknowledge clock pulse, so the SDA line is stable low  
during the high period of the clock pulse. When the  
master is transmitting to the MAX7347/MAX7348/  
MAX7349, the MAX7347/MAX7348/MAX7349 generate  
the acknowledge bit because the MAX7347/MAX7348/  
MAX7349 are the recipients. When the MAX7347/  
MAX7348/MAX7349 are transmitting to the master, the  
master generates the acknowledge bit because the  
master is the recipient.  
Bit Transfer  
One data bit is transferred during each clock pulse  
(Figure 4). The data on SDA must remain stable while  
SCL is high.  
Acknowledge  
The acknowledge bit is a clocked 9th bit (Figure 5),  
which the recipient uses to handshake receipt of each
