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.

Note 1. Stresses listed as the above "Absolute Maximum Ratings" may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. For WQFN-20L 4x4, θJA is measured in natural convection at TA = 25°C on a high-effective thermal conductivity four-layer
test board of JEDEC 51-7 thermal measurement standard. The measurement case position of θJA is on the exposed
pad of the package. For TSSOP-20, θJA is measured in natural convection at TA = 25°C on a low-effective thermal
conductivity single-layer test board of JEDEC 51-3 thermal measurement standard.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
Note 5. Switch characteristics are guaranteed by design; not subject to production testing.
