DESCRIPTION
The BUFxx704 are a series of multi-channel buffers
targeted towards gamma correction in high-resolution
LCD panels. They are pin-compatible with the existing
BUFxx702 and BUFxx703 family and operate at higher
supply voltages up to 18 V (19 V absolute max). The
higher supply voltage enables faster response times
and brighter images in large-screen LCD panels. This
is especially important in LCD TV applications.
The number of gamma correction channels required
depends on a variety of factors and differs greatly from
design to design. Therefore, 10, 6, and 4 channel
options are offered. For additional space and cost
savings, a V
COM
channel with > 100mA drive capability
is integrated into the BUF11704, BUF07704, and
BUF05704.
The BUF11704, BUF07704, BUF06704, and
BUF05704 are available in the TSSOP-28, TSSOP-20,
TSSOP-16, and TSSOP-14 PowerPAD packages for
dramatically increased power dissipation capability.
This way, a large number of channels can be handled
safely in one package.
A flow-through pin out has been adopted to allow simple
PCB routing and maintain the cost-effectiveness of this
solution. All inputs and outputs of the BUFxx704
incorporate internal ESD protection circuits that prevent
functional failures at voltages up to 8 kV (HBM), 2 kV
(CDM), and 300 V (MM).
