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. Features ● Grayscale data: 18-bit digital (3 outputs × 6 bits) parallel transfer method, selectable write direction ● Panel drive outputs: 240 outputs ● Grayscale levels: Capable of switching 2-grayscale mode and 16 grayscale/64 grayscale mode, and capable of reference analog voltage inputs. ● High-speed operation: 5 MHz (max) ● Display mode: Normal display mode ● Power supply voltage: Digital power supply voltage (DVDD) .............2.5 to 3.6 V Analog power supply voltage (AVDD)..............4.5 to 5.6 V ● Operating temperature: −20 to 75°C ● Package: Gold bump chip ● CMOS process ● Cascading multiple devices
