The TSH345 is ideal to drive YC, CVBS, YUV, YPbPr or RGB signals from video DAC outputs. The main advantage of this circuit is its input DC level shifter. It allows driving video signals on 75 video lines without damaging the synchronization tip and without input or output capacitors when using a single 5 V power supply. The DC level shifter is internally fixed and optimized to keep the output video signals between low and high output rails in the best position for the greatest linearity. The TSH345 is available in SO-14 and TSSOP-14 plastic packages for optimum space saving.
