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.
