Description
The FHP3194 is a 4:1 analog multiplexer designed for high
speed video applications. The output amplifier is a high-speed
current feedback amplifier that offers stellar large signal
performance of 335MHz -3dB bandwidth and 80MHz 0.1dB
bandwidth. The gain of the output amplifier is selectable thru 2
external resistors (Rf and Rg), allowing further flexibility. The
2Vpp bandwidth performance, 1600V/µs slew rate, and 0.02% /
0.03° differential gain and phase exceed the requirements of
high definition television (HDTV) and other multimedia
applications. The output amplifier also provides ample output
current to drive multiple video loads.
Two address bits (A0 and A1) are used to select one of the four
buffered inputs. The FHP3194 offers excellent 7.5ns switching
times and better than 70dB channel isolation.
The FHP3194 offers both shutdown and disable capability.
During shutdown, the FHP3194 consumes only 3mA of supply
current and provides maximum input to output isolation. During
disable mode, only the output amplifier is disabled reducing
output glitches and allowing for multiplexer expansion.
