Versatile Input Biasing
which includes Y'P'BP'R 720p/1080i, G'B'R' (R'G'B'),
DC-Coupled With 140-mV Input Shift
and VGA/SVGA/XGA signals.
AC-Coupled with Sync-Tip Clamp
As part of the THS7316 flexibility, the input can be

Supports Driving 2 Lines per Channel
The THS7316 is the perfect choice for all output
Low 18.3-mA at 3.3-V Total Quiescent Current
buffer applications. Its rail-to-rail output stage with
Low Differential Gain/Phase of 0.1% / 0.1°
6-dB gain allows for both ac and dc line driving. The
SOIC-8 Package
ability to drive 2 video lines per channel, or 75-
loads, allows for maximum flexibility as a video line
driver. The 18.3-mA total quiescent current makes it
an excellent choice for USB powered, portable, or
Set Top Box Output Video Buffering
other power sensitive video applications.
PVR/DVDR Output Buffering
USB/Portable Low Power Video Buffering
The THS7316 is available in a small SOIC-8 package
that is RoHS compliant.
