NOTE: 1. Relationship between TFT-LCD panel and Pd (PdCL* (VDD2)² * fCLK1)

CAUTIONS:
If LSIs are stressed beyond those listed above "absolute maximum ratings", they may be permanently destroyed. These are stress ratings only, and functional operation of the device at these or any other condition beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute maximum rated conditions for extended periods may affect device reliability.

The KS0668 is a 384 channel output, TFT-LCD source driver for an 64 gray-scale LCD panel. Data input is based on digital input consisting of 6 bits by 6 dots, which can realize a full-color display of 260,000 colors by output of 64 values gamma-corrected.

The KS0668 has an internal D/A (digital-to-analog) converter for each output and 10 (5-by-2) reference voltages. ecause the output dynamic range is as large as 4.8 - 7.8 Vp-p, it is unnecessary to operate level inversion of the LCD's common electrode. Besides, to be able to deal with dot-line inversion when mounted on a single-side, output gray-scale voltages with different polarity can be output to the odd number output pins and the even output pins.

KS0668 can be adopted to larger panel, and SHL (shift direction selection) pin makes the use of the LCD panel onnection conveniently. Maximum operation clock frequency is 55 MHz at 2.7 V logic operation, single edge and it can be applied to the TFT-LCD panel of XGA to SXGA standard.
