the dg300a_mil/dg301a_mil/dg302a_mil monolithic cmos switches feature three switch configuration options (spst, spdt, and dpst) for precision applications in communications, instrumentation and process control, where low leakage switching combined with low power consumption are required. designed on the vishay siliconix plus-40 cmos process, these switches are latch-up proof, and are designed to block up to 30 v peak-to-peak when off. an epitaxial layer prevents latchup. in the on condition the switches conduct equally well in both directions (with no offset voltage) and minimize error conditions with their low on-resistance. featuring low power consumption (3.5 mw typ) these switches are ideal for battery powered applications, without sacrificing switching speed. designed for break-before-make switching action, these devices are cmos and quasi ttl compatible. single supply operation is allowed by connecting the v? rail to 0 v.

the dg300a_mil series of analog switches will switch positive analog signals while using a single positive supply. this facilitates their use in applications where only one supply is available. the trade-offs of using single supplies are: 1) increased r ds(on) ; 2) slower switching speed. the analog voltage should not go above or below the supply voltages which in single operation are v+ and 0 v.
