 Output short-circuit

1. All voltage values, except differential voltage, are with respect to network terminal.
2. An output current limitation protects the circuit from transient currents. Short-circuits can cause excessive heating. Destructive dissipation can result from short-circuits on amplifiers.




Description

The TSH173 is a single supply triple video buffer featuring an internal gain of 6dB and an internal low pass filter of 8.2MHz cut-off frequency for each channel to fit with Standard Definition requirements for video line interfaces.

Another advantage of the TSH173 is its input DC level shifter to drive the video signal on a 75 video line without any damage to the synchronization tip, 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 signal between low and high output rails in the best position to improve linearity.

This datasheet gives technical information on using the TSH173 as a R-G-B, Y-Pb-Pr, or Y-CCVBS driver for video DAC outputs on a video line.

The TSH173 is available in SO8 plastic package.
