General Description
The G1580 consists of five level shifters and two
Vcom buffers target toward the needs of thin film tran-
sistor liquid crystal display (TFT LCD). The embedded
level shifters can shift digital input signals to the output
voltage levels provided by REFH and REFL pins. The
REFH and REFL input voltage range can be nearly
equal to the supply voltage. The G1580 also incorpo-
rates two Vcom buffers. Each buffer is capable of
driving heavy capacitive loads and offering fast current
loading of 50mA.
The G1580 is available in the TQFN5X5-32 package.
