DS8900-06 September 2011 www.richtek.com 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, θ JA 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 T A = 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.

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.
