GENERAL DESCRIPTION  
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 perfor-  
mance, dramatically lower power consumption, and reduce the  
package size.  
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.  
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 direc-  
tions and the input signal range extends to the supplies.  
PRODUCT HIGHLIGHTS
