... In this example, the CMOS inverter is used as a COM signal driver in consideration of the large display area. (The load capacitance on COM is large because it is common to all the displayed segments.) Usually, one of the HD66100F outputs can be used as a COM signal. The displayed data corresponding to the terminal should that case. Figure 14 Example of Connection ...
