BT8370KPF/28370-22

Product Summary

The BT8370KPF/28370-22 is a single chip transceiver. A pinout diagram of this device is illustrated in Figure 1-1. Figure 1-2 details a BT8370KPF/28370-22 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 kΩ) and can remain unconnected if the active-high input state is desired. All other unused input pins should be either pulled up or grounded.
