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

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.
