RT8900
Level Shifter
General Description
The RT8900 is an 8-Channel level shifter suitable for TFT-
LCD row drivers. The RT8900 will level shift a digital input
signal to an output voltage nearly equal to its output supply
voltages. The RT8900 has 3 supplies : VGH1 and VGH2
are positive supplies with a voltage range from 20V to
35V and VGL is the negative supply with a voltage range
from −5V to −10V. Outputs 0 to 5 are supplied from VGH1
and VGL. Outputs 6 and 7 are supplied from VGH2 and
VGL. This configuration enables outputs 0 to 5 to provide
slicing to the TFT-LCD row drivers to reduce flicker. VGH2
should be remained constant. The RT8900 is available in
TSSOP-20 and WQFN-20L 4x4 packages.
