AD8170 (2:1) and AD8174 (4:1) are very high speed buffered multiplexers. These multiplexers offer an internal current feedback output amplifier whose gain can be programmed via external resistors and is capable of delivering 50mA of output current. They offer -3dB signal bandwidth of 250MHz and slew rate of greater than 1000V/ms. Additionally, AD8170 and AD8174 have excellent video specifications with low differential gain and differential phase error of 0.02% and 0.05° and 0.1dB flatness out to 80MHz. With a low 78dB of crosstalk and better than 88 dB isolation, these devices are useful in many high speed applications. These are low power devices consuming only 9.7mA from a +/-5V supply.

The AD8174 offers a high speed disable feature allowing the output to be put into a high impedance state for cascading stages so that the off channels do not load the output bus. Additionally, the AD8174 can be shut down (SD) when not in use to minimize power consumption (IS = 1.5mA). These products will be offered in 8-lead and 14-lead PDIP and SOIC packages.
