GENERAL DESCRIPTION The ADG795A/ADG795G are monolithic CMOS devices comprising five 2:1 multiplexers/demultiplexers controllable via a standard I 2 C serial interface. The CMOS process provides ultralow power dissipation, yet gives high switching speed and low on resistance. The on-resistance profile is very flat over the full analog input range and wide bandwidth ensures excellent linearity and low distortion. These features, combined with a wide input signal range make the ADG795A/ADG795G the ideal switching solution for a wide range of TV applications including S-video, RGB and YPbPr video switches. The switches conduct equally well in both directions when on. In the off condition, signal levels up to the supplies are blocked. The ADG795A/ADG795G switches exhibit break-before-make switching action. The ADG795G has one general-purpose logic output pins controlled by the I 2 C interface that can also be used to control other non-I 2 C-compatible devices such as video filters. The integrated I 2 C interface provides a large degree of flexibility in the system design. It has three configurable I 2 C address pins that allow up to eight devices on the same bus. This allows the user to expand the capability of the device by increasing the size of the switching array.
