GENERAL DESCRIPTION
The ADG795A/ADG795G are monolithic CMOS devices
comprising five 2:1 multiplexers/demultiplexers controllable via
a standard I
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
to control other non-I
The integrated I

user to expand the capability of the device by increasing the size
of the switching array.
The ADG795A/ADG795G operate from a single 3 V or 5 V
supply voltage and are available in a compact 4 mm × 4 mm
