LC75742E, 75742W
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 microcontroller. 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.

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.
