Description
The TSH344 is a triple single-supply video buffer
featuring an internal gain of 6dB and a large
bandwidth of 340MHz.
The main advantage of this buffer is its very low
output rail very close to GND when supplied in
single supply 0/5V. This output rail is guaranteed
by test at 60mV from GND on 150Ω. Chapter 4 of
this datasheet gives technical support when using
the TSH344 as RGB driver for video DAC output
on a video line (see TSH343 for Y-Pb-Pr signals).
The TSH344 is available in the compact SO8
plastic package for optimum space-saving.
