1/2 Duty VFD Driver with Key Input Function
Overview
The LC75742E and LC75742W are 1/2 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 82 segments. It also includes a key scan circuit and
can support input from up to 30 keys and can thus reduce
the number of lines to the front panel in application
systems.
Features
• Key input from up to 30 keys
(Key scans are only performed when keys are pressed.)
• 82 segment outputs.
• Noise reduction circuits are built into the output drivers.
• Serial data I/O supports CCB format communication
with the system controller.
• Dimmer and sleep mode 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.
