Functional Description
A block diagram for the MM5483 is shown in Figure 1 and a
package pinout is shown in Figure 2 Figure 3 shows a pos-
sible 3-wire connection system with a typical signal format
for Figure 3 Shown in Figure 4 the load input is an asyn-
chronous 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 V

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 dis-
play in the 2-wire mode An AC timing diagram can be seen
in Figure 6 It should be noted that data out is not a TTL-
