GENERAL DESCRIPTION

The ADG774 is a monolithic CMOS device comprising four
2:1 multiplexer/demultiplexers with high impedance outputs.
The CMOS process provides low power dissipation yet gives
high switching speed and low on resistance. The on-resistance
variation is typically less than 0.5W with an input signal ranging
from 0V to 5V.
The bandwidth of the ADG774 is greater than 200MHz and
this, coupled with low distortion (typically 0.5%), makes the
part suitable for switching fast ethernet signals.
The on-resistance profile is very flat over the full analog input
range ensuring excellent linearity and low distortion when switch-
ing audio signals. Fast switching speed, coupled with high signal
bandwidth, also makes the parts suitable for video signal switch-
ing. CMOS construction ensures ultralow power dissipation
making the parts ideally suited for portable and battery powered
instruments.
The ADG774 operates from a single 3.3V/5V supply and is
TTL logic compatible. The control logic for each switch is shown
in the Truth Table.
These switches conduct equally well in both directions when ON,
and have an input signal range that extends to the supplies. In
the OFF condition, signal levels up to the supplies are blocked.
The ADG774 switches exhibit break-before-make switching
action.
PRODUCT HIGHLIGHTS
Wide bandwidth data rates >200 MHz.Ultralow Power Dissipation.Extended Signal Range.
The ADG774 is fabricated on a CMOS process giving an
increased signal range that fully extends to the supply rails.Low leakage over temperature.Break-Before-Make Switching.
This prevents channel shorting when the switches are config-
ured as a multiplexer.Crosstalk is typically –70 dB @ 30 MHz.Off isolation is typically –60 dB @ 10 MHz.

NOTESStresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability. Only one absolute maxi-
mum rating may be applied at any one time.Overvoltages at IN, S or D will be clamped by internal diodes. Current should be
limited to the maximum ratings given.
