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 (100Ω>) 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 interface standard. Functioning as a shift register, this serial interface allows data (at DIN) to be locked in synchronous with the rising edge of clock (SCLK). The shift register's output (DOUT) enables several MAX335s to be daisy chained.ApplicationsAvionicsNetworkingSerial Data Acquisition and Process ControlSignal Routing
