Application information

RT8900 is an 8-channel level shifter operating at high

supply and maintaining low power consumption. The

device requires three supply voltages VGH1, VGH2 and

VGL to supply all logic levels for outputs. VGH1 applies

to the high output level for VOUT0 to VOUT6 and VGH2 is

for VOUT7 to VOUT8. VGL sets the low output level for all

channels. VGH2 must always be larger than or equal to

VGH1. Logic input signals at VIN0 to VIN7 operate from

supply voltages from 0V to 6V.Connect the unused logic

input signal to high or low logic level.

RT8900 with high driving capability is ideal for TFT LCD

panels. In general applications, the input signal for VIN0

to VIN7 supplied from the timing controller of TFT LCD

system; the panel operates in high voltage supplied from

the output signal VOUT0 to VOUT7. RT8900 translates

the timing controller's signal into high-low level signal to

drive the panel. Fast rising / falling time and low propagation

delay makes RT8900 being suitable for driving TFT LCD

panels.
