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.
