Quad SPST CMOS Analog Switches
DG202/DG212
General Description
The DG202/DG212 are normally open, quad singlepole single-throw (SPST) analog switches. These CMOS switches can be continuously operated with power supplies ranging from ±4.5V to ±18V. Maxim guarantees that these switches will not latch up if the power supplies are disconnected with input signals still connected. The DG202/DG212 are similar to the DG201/DG211 except for inverted control inputs. All devices have guaranteed break-before-make switching, as well as essentially constant on-resistance over the analog signal range. All switches conduct current in either direction and add no offset to the output signal.
