Fabricated using the revolutionary complimentary silicon-germanium (SiGe) BiCom3 process, the THS7347 is a low-power, single-supply 2.7-V to 5-V 3-channel integrated video buffer with horizontal (H) and vertical (V) sync signal paths. It incorporates a 500-MHz bandwidth, 1200-V/µs unity-gain buffer ideal for driving analog-to-digital converters (ADCs) and video decoders. In parallel with the unity-gain buffer, a monitor pass-through path allows for passing the input signal on to other systems. This path has a 6-dB gain, 500-MHz bandwidth, 1300-V/µs slew rate, SAG correction capability, and high output impedance while disabled.

Each channel of the THS7347 is individually I²C-configurable for all functions, including controlling the 2:1 input mux. Its rail-to-rail output stage allows for both ac- and dc-coupling applications.
