General Description
The G2581 is a 9-channel level shifter suitable for
TFT-LCD row drivers. This device will level shift a dig-
ital input signal to an output voltage nearly equal to its
output supply voltage.
The G2581 has 3 supplies: VIN, VGH and VGL1. VIN
is low voltage supply with a voltage range from 2.6V to
5.5V. VGH is positive high voltage supply with a volt-
age range from 7V to 40V. VGL1 is negative high
voltage supply with a voltage range from 0V to -30V.
CKO_1~CKO_6 are level shifter outputs with gate
shading function. STO and LCO_1~LCO_2 are level
shifter outputs without gate shading function.
The G2581 features extensive protection functions
that include UVLO, OTP. This device operates over
the temperature range from -40°C to +85°C.
The G2581 is available in a 5mmx5mm, 32-lead QFN
package.
