(1) The BUF07702 is not recommended for new designs. Informa-
tion is provided for reference only. For new designs, the pin-com-
patible BUF07703 is recommended; more information can be
found at www.ti.com.
DESCRIPTION
The BUFxx702 are a series of multi-channel buffers
targeted towards gamma correction in high-resolution
LCD panels. The number of gamma correction
channels required depends on a variety of factors and
differs greatly from design to design. Therefore, various
channel options are offered. For additional space and
cost savings, a VCOM channel with higher current drive
capability is integrated in the BUF11702 and
BUF07702.
The various buffers within the BUFxx702 are carefully
matched to the voltage I/O requirements for the gamma
correction application. Each buffer is capable of driving
heavy capacitive loads and offers fast load current
switching. The VCOM channel has increased output
drive of > 100mA and can handle even larger capacitive
loads.
The BUF07702 and BUF11702 is available in the
TSSOP-PowerPADpackage for dramatically
increased power dissipation capability. This way, a
large number of channels can be handled safely in one
package.
A flow-through pinout has been adopted to allow simple
PCB routing and maintain the cost-effectiveness of this
solution. All inputs and outputs of the BUFxx702
incorporate internal ESD protection circuits that prevent
functional failures at voltages up to 4kV (HBM) as
tested under MIL-STD-883C Method 3015.
