General 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-Ω video lines without damaging the synchronization tip of the video signal, and with no input capacitor, while using a single 5 V power supply.
