_______________General Description
The MAX381/MAX383/MAX385 are precision, low-volt-
age analog switches. The single-pole single-throw
MAX381 and double-pole single-throw MAX385 dual
switches are normally open. The single-pole double-
throw MAX383 has two normally open and two normally
closed poles. All three parts offer low on-resistance
(less than 35Ω), guaranteed to match to within 2Ω
between channels and to remain flat over the specified
analog signal range (4Ωmax). They also offer low leak-
age (less than 250pA at +25°C and less than 2.5nA at
+85°C) and fast switching (turn-on time less than 175ns
and turn-off time less than 100ns).
The MAX381/MAX383/MAX385 are fabricated with
Maxim’s low-voltage silicon-gate process for high sys-
tem accuracy. Design improvements guarantee
extremely low charge injection (<5pC) and low power
consumption (<10µW).
These monolithic switches operate with a single posi-
tive supply (+3V to +15V) or with split supplies (±3V to
±8V) while retaining CMOS-logic input compatibility
and fast switching. CMOS inputs provide reduced input
loading.

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.
Note 1: Signals on NC, NO, COM, or IN exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to
maximum current rating.

Note 2: The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in
this data sheet.
Note 3: Guaranteed by design.
Note 4: ∆RON = ∆RON(max) - ∆RON(min). On-resistance match between channels and flatness are guaranteed only with
specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as
measured over the specified analog signal range.
Note 5: Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at room temperature.
Note 6: See Figure 4. Off isolation = 20log10 VCOM/VNC or VNO, VCOM = output, VNC or NO = input to off switch.
Note 7: Between any two switches. See Figure 5.
Note 8: Leakage testing at single supply is guaranteed by testing with dual supplies.

The MAX381/MAX383/MAX385 switches operate with
±3.0V to ±8V bipolar supplies and a +3V to +15V single
supply. In either case, analog signals ranging from V+ to
V- can be switched. The
Typical Operating Characteristics
graphs show the typical on-resistance variation with ana-
log signal and supply voltage. The usual on-resistance
temperature coefficient is 0.5%/°C (typ).
Overvoltage Protection
Proper power-supply sequencing is recommended for
all CMOS devices. Do not exceed the absolute maxi-
mum ratings, because stresses beyond the listed rat-
ings can cause permanent damage to the devices.
Always sequence V+ on first, then V-, followed by the
logic inputs, NO, or COM. If power-supply sequencing
is not possible, add two small signal diodes (D1, D2) in
series with supply pins for overvoltage protection
(Figure 1). Adding diodes reduces the analog signal
range to one diode drop below V+ and one diode drop
above V-, but does not affect the devices’ low switch
resistance and low leakage characteristics. Device
operation is unchanged, and the difference between
V+ and V- should not exceed 17V. These protection
diodes are not recommended when using a single 3V
supply.
