PRODUCT DESCRIPTION
The AD8180 (single) and AD8182 (dual) are high speed 2-to-1
multiplexers. They offer –3 dB signal bandwidth greater than
750 MHz along with slew rate of 750 V/ s. With better than
80 dB of crosstalk and isolation, they are useful in many high
speed applications. The differential gain and differential phase
error of 0.02% and 0.02 , along with 0.1 dB flatness beyond
100 MHz make the AD8180 and AD8182 ideal for professional
video multiplexing. They offer 10 ns switching time making
them an excellent choice for pixel switching (picture-in-picture)
while consuming less than 3.8 mA (per 2:1 mux) on 5 V sup-
ply voltages.
Both devices offer a high speed disable feature allowing the
output to be configured into a high impedance state. This al-
lows multiple outputs to be connected together for cascading
stages while the “OFF” channels do not load the output bus.
They operate on voltage supplies of 5 V and are offered in 8-
and 14-lead plastic DIP and SOIC packages.
