10 / 19 page CIRCUIT DESCRIPTION STV7710/WAF 10/19 4.3 Description STV7710/WAF includes all the logic and power circuits necessary to drive electrodes of a vacuum fluorescent display (VFD). Binary values of each pixel of the displayed line are loaded into the shift register DATA_A/B data bus. Data is shifted at each low to high transition of the CLK clock. After 96 shifts, the data is available at the output of the shift register. This output can be used to cascade several Ics to drive higher resolution displays. The forward /reverse (F/R) input is used to select the direction of the shift register. Data input/output status is set according to the selected direction (refer to Table 6). The maximum frequency of the shift clock is 40MHz. When the STB signal is high, data are transferred from the shift register to the latch and power output stages. All the output data are kept memorized and held in the latch stage when the latch input STB is set at low level. Vsssub and Vsslog must be connected as close as possible to the logical reference ground of the application. Also, make sure that TEST input pin is connected to ground (Figure 8). STV7710/WAF is supplied with a 5 volt power supply. All the logic inputs can be driven either by 5V CMOS logic, or by 3.3V CMOS logic.
