The PD16650 is a TFT-LCD gate driver. Provided with a level shift circuit at the logic input, this chip can output a high gate scan voltage for a CMOS-level input. The PD16650 has an output change-over function for switching from the 120-output mode to the 128-output mode, and vice versa, thereby supporting the VGA, SVGA, and XGA panels. Its output enable function (OE) enables installing the driver on either side.
