HD66350T (TFT Driver)
256-level Grayscale TFT for XGA/SXGA/UXGA Systems
ADE-207-297(Z)
Preliminary
Rev.0.6
December 1998
Description
The HD66350T is a TFT-LCD source driver LSI suitable for XGA, SXGA, and UXGA systems. It
receives 8-bit-per-pixel digital display data, and generates and outputs voltages for 256 grayscales.
The output circuit includes an operational amplifier, and is capable of alternate output of 256 positive-
polarity grayscale voltages and 256 negative-polarity grayscale voltages on individual output pins (dot
inversion drive).
Users can select 384 or 402 outputs. For XGA and SXGA, respectively, eight and ten 384-output LSIs
are used. For UXGA, twelve 402-output LSIs are used.
Features
High-speed operation
Operating clock: 65 MHz (Vcc = 3.0 to 3.6 V) and 50 MHz (Vcc = 2.5 to 3.0 V)

LCD drive outputs
384/402 outputs can be selected:
Eight 384-output LSIs for XGA,
Ten 384-output LSIs for SXGA, and
Twelve 402-output LSIs for UXGA
Data inversion function
Each port has a data inversion pin (a total of two pins), which reduces the power consumption of
the data buses.
