Description  
The TSH346 is a triple single-supply video buffer  
featuring an internal gain of 6 dB and a 36 MHz  
filtering for HD video outputs on 75-Ω video lines.  
The TSH346 is ideal to drive either YUV, YPbPr or  
RGB signals from video DAC outputs. The main  
advantage of this circuit is that its input DC level  
shifter allows for video signals on 75-Ωvideo lines  
without damaging the synchronization tip of the  
video signal, and with no input 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. This level is as low as possible to minimize  
the output DC level in the video line.  
The TSH346 is available in an SO-8 plastic  
package for optimum space saving.
