Pulse driver for LCD drive
BU9764FV
The BU9764FV is a level converter IC designed for LCD drive, which receives 5V signals and converts them to 16V
signals. The compact SSOP-B16 package contains six internal level converters.
Applications
•Smallto medium-sized TFT liquid crystal panels for movie projectors, LCD projectors, and other similar devices
•1)Features
Six internal level converter channels.
3) Shifts levels to convert 5V signals into 16V signals.
4) Compact SSOP-B16 package.
2) TTL input.
•Absolute maximum ratings (Ta = 25°C)
