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. This
datasheet gives technical information on using
the TSH344 as an RGB driver for video DAC
output on a video line. See the TSH343 datasheet
for Y-Pb-Pr signals.
The TSH344 is available in the compact SO8
plastic package for optimum space-saving.
