Level Shifter


Update Alert Share

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.
