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 150

Ω. 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.
