TSH343I中文资料意法半导体数据手册PDF规格书

描述 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 75Ω 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.
