LC7573NM - 1/2 Duty VFD Driver

Description

1.

Consider the examples shown in Figure 4, where data is set up so that the segment outputs S1 to S19 output a low level on the G1 digit output timing and a high level on the G2 digit output timing.

(Here, the G2 side being lighted) 2.

Features

  • 38 segment outputs.
  • Noise reduction circuits are built into the output drivers.
  • Serial data input supports CCB.
  • format communications with the system controller.
  • Switching between digital and analog dimmers under serial data control.
  • High generality since display data is displayed without the intervention of a decoder.
  • All segments can be turned off with the BLK pin SANYO: DIP30S.
  • CCB is a trademark of SANYO.
