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.
Š 0V to 5.5V Input Voltage Range
Š 0V to 18V Output Voltage Range
Š 50mA Continuous Output Current (per
channel)
Š 250mA Peak Output Current (per channel)
Š 25V/μs Slew Rate
Š Propagation Delay 80ns
Š 50kHz Input Frequency
„ Two Vcom Buffers :
Š Rail-to-Rail Input and Output Voltage Range
Š 50mA Continuous Output Current (per
channel)
Š 200mA Peak Output Current (per channel)
„ TQFN5X5-32 Package Available
The G1580 is available in the TQFN5X5-32 package.
