DESCRIPTION

· The TSH346 is a triple single-supply video buffer with a 6 dB internal gain and 36 MHz filtering for HD video outputs on 75-Ω video lines.
· It is designed to drive YUV, YPbPr, or RGB signals from video DAC outputs.
· The device features an internal DC level shifter, eliminating the need for an input capacitor and ensuring safe operation of video signals on 75-Ω lines without damaging the synchronization tip.
· Optimized for a single 5 V power supply, the TSH346 maintains output video signals between low and high output rails, minimizing the output DC level in the video line.
· Available in an SO-8 plastic package for space efficiency.
