DESCRIPTION

The µ PD16647 is a source driver for TFT-LCD 64 gray scale displays. Its logic circuit operates at 3.3 V and the driver circuit operates at 5.0 V. The input data is digital data at 6 bits x 3 dots, and 260,000 colors can be displayed in 64-value outputs γ -corrected by the internal D/A converter and 10 external power supplies. The clock frequency is 50 MHz MIN. µ PD16647 can be used in TFT-LCD panels conforming to the SVGA standards.
