GENERAL DESCRIPTION
The AD8186 (G = +1) and AD8187 (G = +2) are high speed,
single-supply, triple 2-to-1 multiplexers. They offer –3 dB large signal
bandwidth of over 480 MHz along with a slew rate in excess of
1500 V/µs. With better than –80 dB of all hostile crosstalk and
–95 dB OFF isolation, they are suited for many high speed appli-
cations. The differential gain and differential phase error of 0.05%
and 0.05°, along with 0.1 dB flatness to 85 MHz, make the
AD8186 and AD8187 ideal for professional and component video
multiplexing. They 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 package.
