LC7574NW - 1/2 Duty VFD Driver

Description

Consider the examples shown in Figure 4, where data is set up so that the segment outputs S1 to S37 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

74 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: QFP48E.
CCB is a trademark of SANYO.
