Bt8370/8375/8376 is packaged in an 80-pin Metric Quad Flat Pack (MQFP). A  
pinout diagram of this device is illustrated in Figure 1-1. Figure 1-2 details a  
Bt8370/8375/8376 logic diagram. Pin labels, names, I/O functions, and  
descriptions are provided in Table 1-1.  
The input pins listed below contain an internal pullup resistor (>50 k) and  
can remain unconnected if the active-high input state is desired. All other unused  
input pins should be either pulled up or grounded.
