STMicroelectronics | TSH345IDT

STMicroelectronics is one of the world’s largest semiconductor companies, offering one of the world’s broadest product portfolios, including application-specific products and multi-segment products that range from discrete devices to high-performance microcontrollers, secure smart card chips and MEMS (Micro-Electro-Mechanical Systems) devices. As one of the leader in MEMS and sensor technology, STMicroelectronics offers accelerometers, gyroscopes, proximity sensors (including touch sensors) and temperature sensors.

The TSH345 is a triple single-supply video buffer featuring an internal gain of 6 dB and selectable filtering for HD and SD video outputs on 75 Ω video lines. The TSH345 is ideal to drive YC, CVBS, YUV, YPbPr or RGB signals from video DAC outputs. The main advantage of this circuit is its input DC level shifter. It allows driving video signals on 75 Ω video lines without damaging the synchronization tip and without input or output capacitors when using a single 5 V power supply. 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. The TSH345 is most commonly used in applications such as; High-end Video Systems, High Definition TV (HDTV), Broadcast and Graphic Video and Multimedia Products.

The TSH345IDT is available in SO-14 plastic package for optimum space saving.
