The ADG741 / ADG742 are monolithic CMOS SPST switches. These switches are designed using an advanced submicron process that provides low power dissipation, yet offers high switching speed, low on resistance, and low leakage currents. In addition, −3 dB bandwidths of greater than 200 MHz can be achieved.
The ADG741 / ADG742 can operate from a single 1.8 V to 5.5 V supply, making them ideal for use in battery-powered instruments and with Analog Devices’ new generation of DACs and ADCs.
As shown in the Functional Block Diagrams, with a logic input of 1 the switch of the ADG741 is closed, while that of the ADG742 is open. Each switch conducts equally well in both directions when on.
The ADG741 / ADG742 are available in 6-lead and 5-lead SC70 packages.
PRODUCT HIGHLIGHTS
- 1.8 V to 5.5 V Single-Supply Operation. The ADG741 / ADG742 offer high performance, including low on resistance and fast switching times. They are fully specified and guaranteed with 3 V and 5 V supply rails.
- Very Low RON (3 Ω max at 5 V, 5 Ω max at 3 V). At 1.8 V operation, RON is typically 40 Ω over the temperature range.
- On Resistance Flatness RFLAT(ON) (1 Ω max).
- −3 dB Bandwidth >200 MHz.
- Low Power Dissipation. CMOS construction ensures low power dissipation.
- Fast tON/tOFF.
- Tiny 6-Lead and 5-Lead SC70 Packages.
APPLICATIONS
- Battery-powered systems
- Communication systems
- Sample-and-hold systems
- Audio signal routing
- Video switching
- Mechanical reed relay replacement

Evaluation Kits 1
EVAL-5SC70EBZ
EVAL-5SC70EBZ Evaluation Board
Product Detail
Figure 1 shows the EVAL-5SC70EBZ evaluation board. A 5-lead SC70 device can be clamped or soldered to the center of the evaluation board. Each pin of the device has a corresponding link from K1 to K5 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SubMiniature Version B (SMB) connectors on the evaluation board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the evaluation board for prototyping.
Full specifications of the device under test (DUT) are available in the corresponding product data sheet, which should be consulted in conjunction with this user guide when using the evaluation board.

Tools & Simulations 2
LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.
To launch ready-to-run LTspice demonstration circuits for this part:
Step 1: Download and install LTspice on your computer.
Step 2: Click on the link in the section below to download a demonstration circuit.
Step 3: If LTspice does not automatically open after clicking the link below, you can instead run the simulation by right clicking on the link and selecting “Save Target As.” After saving the file to your computer, start LTspice and open the demonstration circuit by selecting ‘Open’ from the ‘File’ menu.
