APPLICATIONS
The high voltage operation coupled with high current driving
capability and the wide range of CMOS levels accepted by the
ADG3123, make the device ideal for LCD-TFT panel applica-
tions. In this type of application, the controllers that generate
the timing signals required to control the pixel scanning process
inside the panel are usually low voltage CMOS devices.

Most LCD-TFT panels operate at high supply voltages; therefore,
the timing signals generated by the controller require level
translation to drive the panel. Figure 18 shows a typical applica-
tion circuit where the ADG3123 translates eight timing signals
provided by the timing controller into high voltage logic levels
required to drive the panel.
