PRODUCT HIGHLIGHTS

1. Wide bandwidth data rates >400 MHz.

GENERAL DESCRIPTION

The ADG774A 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 over the input signal range.

2. Ultralow Power Dissipation.

3. Low leakage over temperature.

4. Break-Before-Make Switching.

This prevents channel shorting when the switches are config-

ured as a multiplexer.

The bandwidth of the ADG774A is typically 400 MHz and this,

coupled with low distortion (typically 0.3%), makes the part

suitable for switching of high-speed data signals.

5. Crosstalk is typically –70 dB @ 10 MHz.

6. Off isolation is typically –65 dB @ 10 MHz.

The on-resistance profile is very flat over the full analog input

range ensuring excellent linearity and low distortion. CMOS con-

struction ensures ultralow power dissipation.

The ADG774A 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. In the OFF condition, signal levels up to the supplies are

blocked. The ADG774A switches exhibit break-before-make

switching action.
