G1580 Global Mixed-mode Technology Inc. Level Shifters and Voltage Buffers for TFT LCD Panel Features General Description Five Level Shifters : The G1580 consists of five level shifters and two Vcom buffers target toward the needs of thin film transistor liquid crystal display (TFT LCD). The embedded level shifters can shift digital input signals to the output voltage levels provided by REFH and REFL pins. The REFH and REFL input voltage range can be nearly equal to the supply voltage. The G1580 also incorporates two Vcom buffers. Each buffer is capable of driving heavy capacitive loads and offering fast current loading of 50mA. 0V to 5.5V Input Voltage Range 0V to 18V Output Voltage Range 50mA Continuous Output Current (per channel) 250mA Peak Output Current (per channel) 25V/μs Slew Rate Propagation Delay 80ns 50kHz Input Frequency Two Vcom Buffers : Rail-to-Rail Input and Output Voltage Range 50mA Continuous Output Current (per channel) 200mA Peak Output Current (per channel) TQFN5X5-32 Package Available The G1580 is available in the TQFN5X5-32 package.
