8 Channel Voltage Level Shifters for TFT LCD

Features

General Description

0V to 6V Input Voltage Range

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.
