GENERAL DESCRIPTION The ADG792A/ADG792G are monolithic CMOS devices, each prising three 4:1 multiplexer/demultiplexers that are controllable through a standard I2C serial interface. The CMOS process provides ultralow power dissipation yet delivers 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 , bined with a wide input signal range, make the ADG792A/ADG792G the ideal switching solution for a wide range of TV applications, including RGB and YPb Pr video switches. When turned on, the switches conduct equally well in both directions. In the off condition, signal levels, up to the supplies, are blocked. The ADG792A/ADG792G switches exhibit breakbefore-make switching action. The ADG792G also has two general-purpose logic output pins controllable through the I2C interface to control other non-I2C-patible devices, such as video filters. The integrated I2C interface provides a large degree...
