Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft's
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.
Overview
The LC75750E and LC75750W are 1/3 duty VFD drivers
that can be used for electronic tuning frequency display
and other applications under the control of a micro-
controller. These products can directly drive VFDs with
up to 264 segments.
Features
264 segment outputs.
Noise reduction circuits are built into the output drivers.
Serial data input supports CCB format communication
with the system controller.
Dimmer can be controlled by serial data input.
High generality since display data is displayed without
the intervention of a decoder.
All segments can be turned off with the BLK pin.
