Overview
DATA SHEET MOS INTEGRATED CIRCUIT µ PD16780 288/300 OUTPUT TFT-LCD SOURCE DRIVER DESCRIPTION The µ PD16780 is a source driver for TFT-LCDs.
The µ PD16780 corresponds only to LCD of Stripe array color filter.
The µ PD16780 is constitute a shift register which generates the sampling time, and a sample-and-hold circuit which samples the analog voltage.
There are two sample-and-hold circuits which perform sampling holding alternately.
The application with high free degree is possible from driver operation system to LCD-TV because a high picture quality is realized.
FEATURES • 5.

6 VP-P, VDD2 = 5.
0 V) • 288/300 Output channel • fMAX.
= 20 MHz (VDD1 = 3.
0 V) • Corresponds only to LCD of Stripe array color filter • Two on-chip sample-and-hold circuits • Small output deviation between pins (deviation between chip pins: ±20 mV MAX.
) • Switch between right and left shift using the R,/L pin ORDERING INFORMATION Part Number Package TCP (TAB package) µ PD16780N-xxx Remark The TCP’s external shape is custom-order item.
