General Description
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 ±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 and DG212 consume very little power,
making them better suited for portable applications.
Maxim has also eliminated the need for the third logic
power supply (VL) that is required for the operation of
the original manufacturer’s DG212 without sacrificing
compatibility.

Pin Description
Switching Time Test Circuit
Switch output waveform shown for VS= constant with
logic input waveform as shown. Note that VSmay be
+ve or -ve as per switching times test circuit. VOis the
steady state output with switch on. Feedthrough via
gate capacitance may result in spikes at leading and
trailing edge of output waveform.
Protecting Against Fault
Conditions
Fault conditions occur when power supplies are turned
off when input signals are still present, or when over-
voltages occur at the inputs during normal operation. In
either case, source-to-body diodes can be forward
biased and conduct current from the signal source. If

Typical RDS(ON) vs. Power Supplies for Maxim’s DG202, and DG212
this current is required to be kept to low (µA) levels
then the addition of external protection diodes is rec-
ommended.
To provide protection for overvoltages up to 20V above
the supplies, a 1N4001 or 1N914 type diode should be
placed in series with the positive and negative supplies
as shown in Figure 2. The addition of these diodes will
reduce the analog signal range to 1V below the posi-
tive supply and 1V above the negative supply.
