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 500MHz -3dB bandwidth and
90MHz 0.1dB bandwidth. The gain of the output amplifier
is selectable through two external resistors (R
f
and R
g
),
allowing further design flexibility. The 2V
pp
bandwidth
performance and 2200V/µs slew rate 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 inputs. The FHP3194 offers better than 70dB channel
isolation.
The FHP3194 offers both shutdown and disable capability.
During shutdown, the FHP3194 consumes only 2.5mA
of supply current. During disable mode, only the output
amplifier is disabled, reducing output glitches and allowing
for multiplexer expansion.

Absolute Maximum Ratings
The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The
device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not
guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table defines the conditions
for actual device operation.

2. SD and EN pins are grounded. IN1 and IN3 = +0.5V, IN2 and IN4 = -0.5V, see truth table to properly set A0 and A1 based on the channels driven. Switching time is the transition
time from 50% of A0 or A1 input value (+2.5V) to the time at which the switched channel is at 90% (or 99%) of its final value.
3. Driving one channel and looking at worst case value from remaining channels.
