LC7574NW, 1/2 Duty VFD Driver

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.

The digit output G1 and G2 waveforms in Example 1 are output w
