Low-Cost Monolithic Quad SPST CMOS Analog Switches
* Logic Inputs Accept Negative Voltages
* On-Resistance—rDS(on): 115 _
The DG211 and DG212 are low cost quad single-pole single-throw analog switches for use in general purpose switching applications in communication, instrumentation and process control. These devices differ only in that the digital control logic is inverted (see Truth Table). The use of both p- and n-channel devices minimizes on-resistance variation over the analog signal range.
Designed with the Siliconix PLUS-40 CMOS process to combine low power dissipation with a high breakdown voltage rating of 40 V, both switches will handle _15-V input signals with ease, and have a continuous current rating of 20 mA. An epitaxial layer prevents latchup.
Both devices feature true bi-directional performance (with no offset voltage) in the on condition, and will block signals to 30 V peak-to-peak in the off condition.
