Quad SPST CMOS Analog Switches
General Description
Features
The DG202 and DG212 are normally open, quad sin-
gle-pole single-throw (SPST) analog switches. These
CMOS switches can be continuously operated with
power supplies ranging from ±±.ꢀ5 to ±1ꢁ5. Maꢂim
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
eꢂcept 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,
Maꢂim’s DG202 and DG212 consume very little power,
making them better suited for portable applications.
Maꢂim has also eliminated the need for the third logic
power supply (5 ) that is required for the operation of
L
the original manufacturer’s DG212 without sacrificing
compatibility.
