Quad SPST CMOS Analog Switches
General Description
The DG202/DG212 are normally open, quad single-
pole 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.
Compared to the original manufacturer’s products,
Maxim’s DG202/DG212 consume very little power,
making them better suited for portable applications.
Maxim has also eliminated the need for the third logic
power supply (V_L) that is required for the operation of
the original manufacturer’s DG212 without sacrificing
compatibility.
