Description  
The TSH345 is available in the SO14 plastic  
package for optimum space-saving.  
The TSH345 is a triple single-supply video buffer  
featuring an internal gain of 6 dB and selectable  
filtering for HD and SD video outputs on 75 Ω  
video lines. The TSH345 is ideal to drive either  
Y-C, CVBS, Y-U-V, Y-Pb-Pr or R-G-B signals from  
video DAC outputs.  
The main advantage of this circuit is its input DC  
level shifter. It allows you to drive video signals on  
75 Ω video lines without damage to the  
synchronization tip, and without either input or  
output capacitor while 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.
