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， single-pole， single-throw （SPST） switches controlled via a 3-wire serial interface. On resistance is matched closely 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 uses 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 devices to be daisy chained. At power-up， all switches are in the off condition， and the internal registers contain all zeros.
