L _{GENERAL DESCRIPTION}
The ADG795A/ADG795G are monolithic CMOS devices
O ^{comprising five 2:1 multiplexers/demultiplexers controllable via}
a standard I²C serial interface. The CMOS process provides
ultralow power dissipation, yet gives high switching speed and
low on resistance.
S _{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
B range make the ADG795A/ADG795G the ideal switching
solution for a wide range of TV applications including S-video,
RGB and YPbPr video switches.
O ^{The switches conduct equally well in both directions when on.}

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.
The ADG795A/ADG795G operate from a single 3 V or 5 V
supply voltage and are available in a compact 4 mm × 4 mm
body, 24-lead, lead-free package (LFCSP).
PRODUCT HIGHLIGHTS
1. Wide bandwidth: 325 MHz.
2. Ultralow power dissipation.
3. Extended input signal range.
In the off condition, signal levels up to the supplies are blocked.
4. Integrated I²C serial interface.
The ADG795A/ADG795G switches exhibit break-before-make
5. Compact 4 mm × 4 mm, 24-lead, lead-free LFCSP.
switching action. The ADG795G has one general-purpose logic
output pins controlled by the I²C interface that can also be used
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. It has three configurable I²C address pins
6. ESD protection tested as per ESD Association standards:
4 kV HBM (ANSI/ESD STM5.1-2001)
200 V MM (ANSI/ESD STM5.2-1999)
1 kV FICDM (ANSI/ESDSTM5.3.1-1999)
