GENERAL DESCRIPTION
The ADG792A/ADG792G are monolithic CMOS devices, each
comprising three 4:1 multiplexer/demultiplexers that are con-
trollable 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, combined with a wide input signal
range, make the ADG792A/ADG792G the ideal switching
solution for a wide range of TV applications, including RGB
and YPbPr 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 break-
before-make switching action. The ADG792G also has two
general-purpose logic output pins controllable through the I2C
interface to control other non-I2C-compatible devices, such as
video filters. The integrated I2C interface provides a large degree
of flexibility in the system design. To build larger switching
