PRODUCT DESCRIPTION
The AD8183 (G = +1) and AD8185 (G = +2) are high speed
triple 2:1 multiplexers. They offer –3 dB signal bandwidth up to
380 MHz, along with slew rate of 1000 V/ s. With better than
–90 dB of channel-to-channel crosstalk and isolation at 10 MHz,
they are useful in many high-speed applications. The differential
gain and differential phase errors of 0.01% and 0.02 respectively,
along with 0.1 dB flatness to 90 MHz make the AD8183 and
AD8185 ideal for professional video and RGB multiplexing. They
offer 15 ns channel-to-channel switching time, making them
an excellent choice for switching video signals, while consuming
less than 25 mA on 5 V supply voltages.
Both devices offer a high speed disable feature that can set the
output into a high impedance state. This allows the building of
larger input arrays while minimizing “OFF” channel output
loading. They operate on voltage supplies of 5 V and are offered
in a 24-lead TSSOP package.

    Third, the additional power and ground pins also yield lower impedance on the power and ground lines, and therefore minimize the effects of shared impedances on crosstalk. Signal routing is also important for keeping crosstalk low. Shielding and separation should ...
