JBT6L77-AS

Source Driver for TFT LCD Panels

The JBT6L77-AS is a 64 gray-level and 240-channel-output source driver for TFT LCD panels.

Grayscale data accepts 6-bit digital data inputs, which combined with the internal DA converter and 11 external

power supplies, allows display of up to 260,000 colors.

Based on high-speed CMOS, the JBT6L77-AS offers both low power consumption and high-speed operation.
