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.

FEATURES
• CMOS level input
• 402/384 outputs
• 6 bits (gray scale data) x 3 dots input
• 64-value output by 10 external power supplies and internal D/A converter
• Output dynamic range : VSS2 + 0.1 V to VDD2 − 0.1 V
• High-speed data transfer: fMAX =50 MHz MIN.(internal data transfer rate at supply voltage VDD1 of logic circuit =3.0 V)
• Level of γ -corrected power supply can be inverted
• Input data inversion function (INV)
• Precharge-less output buffer
• Logic supply voltage (VDD1) : 3.3 V ± 0.3 V
• Driver supply voltage (VDD2) : 5.0 V ± 0.5 V
• Slim TCP
