    4 mm × 4 mm LFCSP

The ADG1414 is a monolithic complementary metal oxide semiconductor (CMOS) device containing eight independently selectable switches designed on an industrial CMOS (iCMOS®) process. iCMOS is a modular manufacturing process combining high voltage CMOS and bipolar technologies. iCMOS components can tolerate high supply voltages while providing increased performance, dramatically lower power consumption, and reduce the package size.

The ADG1414 is a set of octal SPST (single-pole, single-throw) switches controlled via a 3-wire serial interface. On resistance is closely matched between switches and is very 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 eight bits; each bit corresponds to one channel.

The ADG1414 utilizes a versatile 3-wire serial interface that operates at clock rates of up to 50 MHz and is compatible with standard SPI®, QSPI, MICROWIRE, and DSP interface standards. The output of the shift register, SDO, enables a number of these parts to be daisy chained. On power-up, all switches are in the off condition, and the internal registers contain all zeros.

  1. 50 MHz serial interface.
  2. 9.5 Ω on resistance.
  3. 1.6 Ω on-resistance flatness.
  4. 24-lead TSSOP and 4 mm × 4 mm LFCSP packages.

Evaluation Kits

eval board
EVAL-24TSSOP

Evaluation Board for 24-Lead TSSOP Devices in the Switches and Multiplexers Portfolio

Features and Benefits

  • 24-lead TSSOP evaluation board 
  • Clamp allows the main device to be easily changed 
  • Gold pin connectors allow the addition of passive components 
  • SMB connectors for the input/output of signals 
  • Additional space on-board to allow for prototyping 

Product Details

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.
