KS0670

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 KS0670 is a 384 / 402 channel output, TFT-LCD source driver for an 256 gray scale LCD panel. Data input is based on digital input consisting of 8 bits by 6 dots, which can realize a full-color display of 16,700,000 color by output of 256 values gamma-corrected.

The KS0670 has an internal D/A (Digital-to-Analog) converter for each output and 16 (8-by-2) reference voltages. Because the output dynamic range is as large as 7.8 - 14.8 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.

KS0670 can be adopted to larger panel, and SHL (shift direction selection) pin makes the use of the LCD panel connection conveniently. Maximum operation clock frequency is 75 MHz at 3.0 V logic operation, single edge and it can be applied to the TFT-LCD panel of UXGA standard.
