The CMOS process provides low power dissipation yet gives high switching speed and low on resistance. The on resistance variation is typically less than 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 makes the part suitable for switching USB 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 dissipation, making the parts ideally suited for portable and batterypowered instruments.

No license is granted by implication or otherwise under any patent or patent rights of Analog Devices. Trademarks and registered trademarks are the property of their respective owners. The ADG774 operates from a single 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 Wide dB Bandwidth, 240 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.
