LC75725E
1/4 to 1/11 Duty Dynamic Drive VFD Driver
Overview
The LC75725E is a 1/4 to 1/11 duty dynamic drive VFD
driver. It provides 43 segment outputs and 11 digit
outputs. It facilitates the construction of display systems
operating under the control of a controller.
Features
• Dynamic drive display technique to display four to
eleven digits on the VFD.
• Serial data input supports CCB* format communication
with the system controller.
• The dimmer level is controlled by serial data input.
(The dimmer has a resolution of 10 bits.)
• High generality since display data is displayed without
the intervention of a decoder.
• All segments can be turned off with the BLK pin.
• CR oscillator circuit.
