MN12511
Fluorescent Display Tube Driver LSI
s Overview
The MN12511 is a fluorescent display tube driver LSI. It
accepts data for display transferred over a serial interface,
generates the digit and/or segment drive signals, and out-
puts those signals from 16 high-voltage ports.
This LSI allows the number of digits displayed to be
increased easily by the cascade connection of additional
MN12511 LSIs. Also, the MN12511 does not preassign
the outputs to digits or segments, so it can be used with a
wide range of display types.
s Features
• Sixteen high-voltage handling output ports
Number of digit outputs (DGT): 1 to 15 outputs can be
arbitrarily assigned
Number of segment outputs (SEG): 1 to 15 outputs can
be arbitrarily assigned
• FLP display
• The display mode can be set to any combination of
from 1 DGT × 15 SEG to 15 DGT × 1 SEG
• The display on/off state can be controlled from the
OE pin.
• Four-wire serial interface (Includes a chip select signal)
• Built-in shift register
• The MN12511 can be connected in cascade.
• Supply voltage
Digital block (V_DD): + 4.5 to 5.5 V
High-voltage (V_pp): V_DD − 35 V
s Applications
• Video, audio, and other equipment that uses fluorescent
display tubes
