JBT6K47-AS

www.DataSheet4U.com JBT6K47-AS Silicon Monolithic Preliminary TOSHIBA CMOS Digital Integrated Circuits JBT6K47-AS Source Driver for TFT LCD Panels The JBT6K47-AS is a 64 gray-level, 240-channel-output source driver for TFT LCD panels. 6-bit digital input enable to display colors using internal DA converter and five external power supplies. Also, JBT6K47-AS incorporates power saving function to control recognition of the grayscale data input. When display performance is not necessary, such as in a portable device, JBT6K47-AS ignores the grayscale input data. Based on high-speed CMOS, the JBT6K47-AS offers both low power consumption and high-speed operation.
