Description

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 75

Ω

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.
