ASTLC5202A - RGB 480/402 CHANNELS TFT-LCD SOURCE DRIVER

The ASTLC5202A is a source driver for AV type color TFT LCDs, i.e. with analog R, G, B video interfaces. The video signals are sampled and held serially, then sent out synchronously through parallel output channels. A clock selection function is provided in order to simplify circuit applications.

This chip provides a 480/402 channels-select function as well as bi-directional shift control for easier circuit layout and cascade function for dot-expansion.

For superior display qualities the output voltages have a dynamic range close to full scale. And for COG applications, special pin locations and dummy pads are supported. That can enhance reliability and performance.
