The output of the shift register, SDO, enables a high voltage CMOS and bipolar technologies. iCMOS components number of these devices to be daisy chained. can tolerate high supply voltages while providing increased perfor- At power-up, all switches are in the off condition, and the mance, dramatically lower power consumption, and reduce the internal registers contain all zeros. package size. PRODUCT HIGHLIGHTS The ADG1414 is a set of octal, single-pole, single-throw (SPST) 1. 50 MHz serial interface. switches controlled via a 3-wire serial interface. On resistance is 2. 9.5 on resistance. matched closely between switches and is very flat over the full 3. 1.6 on-resistance flatness. signal range. Each switch conducts equally well in both directions 4. 24-lead TSSOP and 4 mm 4 mm LFCSP packages. 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. Rev.
