HD66774 Datasheet 240-channel Gate Driver

Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: HD66774 Rev. 1.0 July 2002 HD66774 240-Channel Gate Driver for Color-TFT Liquid Crystal Displays mRev.1.0 oJuly 2002 .

General Description

UHD66774 is a gate-driver IC for systems with color-TFT-liquid-crystal dot-matrix graphic displays.

t4It incorporates a circuit for driving 240 channels of TFT gate-line driving and all the power-supply circuits that are required for liquid crystal displays, and realizes the liquid crystal display by adding only an external capacitor.

eeWhen used with the HD66770 396-channel source driver with on-chip RAM, and used with the HD66772 528-channel source driver with on-chip RAM, this LSI is suitable for color TFT displays hof cellular phones having 132-by-176 and 176-by-240 dots, respectively.
