_______________General Description
The MAX335 analog switch with serial digital interface
offers eight separately controlled single-pole-single-
throw (SPST) switches. All switches conduct equally in
either direction, and on-resistance (100W) is constant
over the analog signal range.
These CMOS switches can operate continuously with
power supplies ranging from ±4.5V to ±20V and handle
rail-to-rail analog signals. Upon power-up, all switches are
off, and the internal serial and parallel shift registers are
reset to zero. The MAX335 is equivalent to two DG211
quad switches but controlled by a serial interface.
The interface is compatible with the Motorola SPI inter-
face standard. Functioning as a shift register, this serial
interface allows data (at DIN) to be locked in synchro-
nous with the rising edge of clock (SCLK). The shift reg-
ister's output (DOUT) enables several MAX335s to be
daisy chained.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
