MAX394
Low-Voltage, Quad, SPDT,
CMOS Analog Switch
General Description
The MAX394 is a precision, low-voltage, quad, singlepole/double-throw (SPDT) analog switch. The four independent switches operate with bipolar supplies ranging
from ±2.7V to ±8V, or with a single supply of +2.7V to
+15V. The MAX394 offers low on-resistance (less than
35Ω), guaranteed to match within 2Ω between channels
and to remain flat over the analog signal range (Δ4Ω
max). It also offers break-before-make switching (10ns
typical), with turn-off times less than 75ns and turn-on
times less than 130ns. The MAX394 is ideal for portable
operation since quiescent current runs less than 1μA with
all inputs high or low.
This monolithic, quad switch is fabricated with Maxim’s
low-voltage silicon-gate process. Design improvements
guarantee extremely low charge injection (10pC), low
power consumption (10μW), and electrostatic discharge
(ESD) greater than 2000V.
Logic inputs are TTL and CMOS compatible and guaranteed over a +0.8V to +2.4V range for supply voltages
up to +8V. When supplies exceed +8V, the inputs are
typically +0.8V to +4V. Logic inputs and switched analog
signals can range anywhere between the supply voltages
without damage.

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.
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 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: ΔRON = ΔRON(max) - ΔRON(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 6. Off-isolation = 20log10 VCOM/VNC or VNO, VCOM = output, VNC or NO = input to off switch.
Note 7: Between any two switches. See Figure 3.
Note 8: Leakage testing at single supply is guaranteed by testing with dual supplies.

supplies or if the analog signal can dip below ground
in single-supply operation, add two small signal diodes
(D1, D2), as shown in Figure 1. Adding protection diodes
reduces the analog signal range to a diode drop above
V- for D2. Leakage is not affected by adding the diodes.
On-resistance increases by a small amount at low supply
voltages. Maximum supply voltage (V- to V+) must not
exceed 17V.
The MAX394 switch operates with ±2.7V to ±8V bipolar
supplies and a +2.7V 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 analog signal
and supply voltage. The usual on-resistance temperature
coefficient is 0.5%/°C (typ).
Do not exceed the absolute maximum ratings, because
stresses beyond the listed ratings may cause permanent
damage to the device. Proper power-supply sequencing
is recommended for all CMOS devices. Always apply V+,
followed by V- (when using split supplies) before applying
analog signals or logic inputs, especially if the analog or
logic signals are not current-limited. If this sequencing
is not possible and if the analog or logic inputs are not
current-limited to less than 30mA, add a single diode
(D1) for single-supply operation (Figure 1). If using dual

Adding diodes D1 and D2 also protects against some
overvoltage situations. With the circuit of Figure 1, if the
supply voltage is below the absolute maximum rating and
if a fault voltage up to the absolute maximum rating is
applied to an analog signal pin, no damage will result. For
example, with ±5V supplies, analog signals up to ±8.5V
will not damage the circuit of Figure 1. If only a single fault
signal is present, the fault voltage can go to +12V or -12V
without damage.
