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.
