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 families 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 VCOM 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 pinout 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).
