The document describes the features of the TSH344, a triple single-supply video buffer with a bandwidth of 340MHz. It operates on a 5V single supply and guarantees a low output rail of maximum 60mV. The buffer has an internal gain of 6dB to ensure matching between its three channels. It offers very low harmonic distortion and a slew rate of 740V/ms. It is specified for 150Ω and 100Ω loads and has been tested on a 5V power supply. The document also provides information on using the TSH344 as an RGB driver for video DAC output on a video line. The TSH344 is available in the compact SO8 plastic package for space-saving.
The TSH344 is a triple single-supply video buffer designed for high-end video systems, including HDTV and broadcast applications. It features an internal gain of 6dB to match three channels and operates on a 5V single supply with a guaranteed low output rail of 60mV max.
The device is specified for 150Ω and 100Ω loads and includes specifications for bandwidth, slew rate, distortion, and power supply rejection. It is available in a compact SO8 plastic package.
