The MM5483 is a monolithic integrated circuit utilizing
CMOS metal-gate low-threshold enhancement mode
devices. It is available in a 40-pin PDIP package. The
chip can drive up to 31 segments of LCD and can be
cascaded to increase this number. This chip is
capable of driving a 4½-digit 7-segment display with
minimal interface between the display and the data
source.

The MM5483 stores the display data in latches after it
is latched in, and holds the data until another load
pulse is received.

FUNCTIONAL DESCRIPTION
A block diagram for the MM5483 is shown in Figure 1 and a package pinout is shown in Figure 3. 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.
