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 0.5 Ω with an input signal ranging
from 0 V to 5 V.
The bandwidth of the ADG774 is greater than 200 MHz; this,
coupled with low distortion (typically 0.5%), makes the part
suitable for switching USB 1.1 data signals and fast Ethernet
signals.
The on resistance profile is very flat over the full analog input
range ensuring excellent linearity and low distortion when
switching audio signals. Fast switching speed, coupled with high
signal bandwidth, also makes the parts suitable for video signal
switching. CMOS construction ensures ultralow power dissipa-
tion, making the parts ideally suited for portable and battery-
powered instruments.

The ADG774 operates from a single 3.3 V/5 V 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
1. Wide –3 dB Bandwidth, 240 MHz.
2. Ultralow Power Dissipation.
3. Extended Signal Range.
4. Low Leakage Over Temperature.
5. Break-Before-Make Switching.
6. Crosstalk Typically –70 dB @ 30 MHz.
7. Off Isolation Typically –60 dB @ 10 MHz.

The ADG774 is fabricated on a CMOS process giving an
increased signal range that fully extends to the supply rails.
This prevents channel shorting when the switches are config-
ured as a multiplexer.
