NOTES
¹Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ²Specification is for device in free air (TA = 25°C). ³24-lead plastic TSSOP; JA = 128°C/W. Maximum internal power dissipation (PD) should be derated for ambient temperature (TA) such that PD < (150°CT_A)/JA.

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/ms. 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 AD8183 (G = +1) and AD8185 (G = +2) 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.
