General Description
The G1581 consists of eight level shifters target to-
ward the needs of thin film transistor liquid crystal dis-
play (TFT LCD). The embedded level shifters can level
shift digital input signals to the output voltage levels
nearly equal to the supply voltages. It is capable of
+35V to -10V output voltage swing. The G1581 has
two positive power supplies VGH1 and VGH2, and
one negative power supply VGL. VGH1 and VGL are
the power supplies of the outputs 1 to 6. VGH2 and
VGL are the power supplies of the outputs 7 and 8.
This configuration enables the outputs 1 to 6 to pro-
vide slicing to the row drivers to reduce flicker, and the
outputs 7 and 8 to control possible supply lines. VGH2
should remain constant and it needs to be greater than
or equal to VGH1 at all times.
The G1581 is available in the TSSOP-20 & TQFN4X4-20
package.
