Serial Controlled, 8-Channel SPST Switch

_______________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 (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 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.
