Functional Description
This product is specifically designed to drive multiplexed or
non-multiplexed high voltage alphanumeric or dot matrix
vacuum fluorescent (VF) displays. Character generation is
done externally in the microprocessor, with a serial data path
to the display driver. The MM58342 uses three signals,
DATA IN, CLOCK and ENABLE, where ENABLE acts as an
external load signal. Display blanking can be achieved by
means of the BLANKING CONTROL input, and a logic “1”
will turn off all sections of the display. A block diagram of the
MM58342 is shown in Figure 1
Figure 2 shows the pinout of the MM58342 device, where
output 1 (pin 12) is equivalent to bit 1 (i.e., the first bit of data
to be loaded into the shift register following ENABLE high).A
logic “1” at the input will turn on the corresponding display
digit/segment/dot output.
A significant reduction in discrete board components can be
achieved by use of the MM58342, because external
