The TSH343 is a triple single-supply video buffer featuring an internal gain of 6dB and a large 280MHz bandwidth.
The main advantage of this circuit is that its input DC level shifter allows for video signals on 75Ω video lines without damage to the synchronization tip of the video signal, while using a single 5V power supply with no input capacitor. 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.
This datasheet provides information on using the TSH343 as a Y-Pb-Pr driver for video DAC output on a video line. See the TSH344 datasheet for R-G-B signals.
The TSH343 is available in the compact SO8 plastic package for optimum space-saving.
