Figure 4 shows a possible 3-wire connection system with a typical signal format for Figure 4. Shown in Figure 5, the load input is an asynchronous input and lets data through from the shift register to the output buffers any time it is high. The load input can be connected to VDD for 2-wire control as shown in Figure 6. In the 2-wire control mode, 31 bits (or less depending on the number of segments used) of data are clocked into the MM5483 in a short time frame (with less than 0.1 second there probably will be no noticeable flicker) with no more clocks until new information is to be displayed. If data was slowly clocked in, it can be seen to “walk” across the display in the 2wire mode. An AC timing diagram can be seen in Figure 7. It should be noted that data out is not a TTLcompatible output. Figure 4. Three-Wire Control Mode Figure 5. Data Format Diagram Figure 6.
