The ADG714 is a complementary metal-oxide semiconductor (CMOS), octal single-pole, single-throw (SPST) switch controlled via a 3-wire serial interface. On resistance is closely matched between the switches and is flat over the full signal range. Each switch conducts equally well in both directions, and the input signal range extends to the supplies. Data is written to these devices in the form of 8 bits, each bit corresponding to one channel.
The ADG714 uses a 3-wire serial interface that is compatible with serial peripheral interface (SPI), QSPI™, MICROWIRE™ interface standards, and most digital signal processing (DSP) interface standards. The output of the shift register DOUT enables a number of these devices to be daisy-chained.
On power-up, all switches are in the OFF condition, and the internal registers contain all zeros.
A low power consumption and operating supply range of 2.7 V to 5.5 V makes this part ideal for many applications. The ADG714 may also be supplied from a dual ±2.5 V supply. The ADG714 is available in a 24-lead TSSOP and a 24-lead LFCSP.

Product Lifecycle Production
At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
Evaluation Kits (1)
The EVAL-24TSSOPEBZ evaluation board evaluates 24-lead TSSOP devices in the Switches and Multiplexers Portfolio that are purchased separately. A clamp is supplied with the EVAL-24TSSOPEBZ to secure a 24-lead TSSOP device to the evaluation board without the need for soldering, making the board reusable for multiple devices.
A 24-lead TSSOP 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 K24 that can be set to either VDD or GND. A wire screw terminal supplies VDD and GND. SMB connectors on the board allow additional external signals to be supplied to the device. In addition, there is space available at the top of the 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.
