TSH344 340MHz single-supply triple video buffer Features Bandwidth: 340MHz 5V single-supply operation Low output rail guaranteed at 60mV max Internal gain of 6dB for a matching between 3 channels Pin connections (top view) Very low harmonic distortion Slew rate: 740V/ms Pin1 identification Top View Specified for 150 and 100 loads Tested on 5V power supply 8 OUT1 IN1 1 6dB Min. and max. data tested during production Applications 7 OUT2 IN2 2 6dB High-end video systems IN3 3 6dB 6 OUT3 High definition TV (HDTV) Broadcast and graphic video +Vcc 5 GND 4 Multimedia products SO8 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. 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.
