GENERAL DESCRIPTION
The AD8188 (G = 1) and AD8189 (G = 2) are high speed,
single-supply, triple 2-to-1 multiplexers. They offer 3 dB small
signal bandwidth of 350 MHz and 3 dB large signal bandwidth
of 300 MHz, along with a slew rate in excess of 1000 V/μs. With
84 dB of all hostile crosstalk and 95 dB off isolation, the parts
are well suited for many high speed applications. The
differential gain and differential phase error of 0.05% and 0.05°
respectively, along with 0.1 dB flatness to 70 MHz, make the
AD8188 and AD8189 ideal for professional and component
video multiplexing. The parts offer 4 ns switching time, making
them an excellent choice for switching video signals, while
consuming less than 20 mA on a single 5 V supply (100 mW).
Both devices have a high speed disable feature that sets the
outputs into a high impedance state. This allows the building of
larger input arrays while minimizing off-channel output
loading. The devices are offered in a 24-lead TSSOP.
