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 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.
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.
