__________________General Description
The MAX301/MAX303/MAX305 are precision, dual, high-
speed analog switches. The single-pole single-throw (SPST)
MAX301 and double-pole single-throw (DPST)MAX305 dual
switches are normally open (NO). The single-pole double-
throw (SPDT) MAX303 has two NO and two normally closed
(NC) poles. All three parts offer low on resistance (less than
35Ω), guaranteed to match to within 2Ωbetween channels
and to remain flat over the full analog signal range (Δ3Ωmax).
They also offer low leakage (less than 250pA at +25°C and
less than 6nA at +85°C) and fast switching (turn-on time less
than 150ns and turn-off time less than 100ns).
The MAX301/MAX303/MAX305 are fabricated with Maxim’s
new improved silicon-gate process for high system accuracy.
Design improvements guarantee extremely low charge injec-
tion (15pC) and low power consumption (35µW). A 44V maxi-
mum breakdown voltage allows rail-to-rail analog signal
capability.
These monolithic switches operate with a single positive sup-
ply (+10V to +30V) or with split supplies (±4.5V to ±20V) while
retaining CMOS-logic input compatibility and fast switching.
CMOS inputs provide reduced input loading.

Note 1:
Signals on NO_, NC_, or COM_ beyond V+ or V- are clamped by internal diodes. Limit forward current to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Operation with Supply Voltages
Other than ±15V

The MAX301/MAX303/MAX305 switches operate with
±4.5V to ±20V bipolar supplies and a +10V to +30V sin-
gle supply. In either case, analog signals ranging from V+
to V- can be switched. The Typical Operating
Characteristicsgraphs show the typical on-resistance
variation with analog signal and supply voltage. The usual
on-resistance temperature coefficent is 0.5%/°C (typ).
Logic Inputs

The MAX301/MAX303/MAX305 operate with a single pos-
itive supply or with bipolar supplies. The devices maintain
TTL compatibility with supplies anywhere in the ±4.5V to
±20V range as long as VL= +5V. If VLis connected to V+
or another supply at voltages other than +5V, the devices
will operate at CMOS-logic level inputs.
Overvoltage Protection

Proper power-supply sequencing is recommended for all
CMOS devices. It is important not to exceed the absolute
maximum ratings because stresses beyond the listed rat-
ings may cause permanent damage to the devices.
Always sequence V+ on first, followed by VL, V-, and
logic inputs. If power-supply sequencing is not possible,
add two small signal diodes in series with the supply pins
for overvoltage protection (Figure 1). Adding diodes
reduces the analog signal range to 1V below V+ and 1V
below V-, but low switch resistance and low leakage char-
acteristics are unaffected. Device operation is
unchanged, and the difference between V+ to V- should
not exceed +44V.
