MAX396/MAX397
Precision, 16-Channel/Dual 8-Channel,
Low-Voltage, CMOS Analog Multiplexers
General Description
The MAX396/MAX397 low-voltage, CMOS analog
multiplexers (muxes) offer low on-resistance (100Ω max),
which is matched to within 6Ω between switches and
remains flat over the specified signal range (10Ω max).
They also offer low leakage over temperature (input
off-leakage current less than 1nA at +85°C) and fast
switching speeds (transition time less than 250ns). The
MAX396 is a 16-channel device, and the MAX397 is a
dual, 8-channel device.
Benefits and Features
●● Pin-Compatible with MAX306/MAX307,
DG406/DG407, DG506A/DG507A
●● Single-Supply Operation (+2.7V to +16V)
Dual-Supply Operation (±2.7V to ±8V)
●● Low On-Resistance (100Ω max)
●● Guaranteed RON Match Between Channels (6Ω max)
●● Guaranteed RON Flatness over Specified Signal Range
(10Ω max)
The MAX396/MAX397 are fabricated with Maxim’s lowvoltage silicon-gate process. Design improvements yield
extremely low charge injection (5pC max) and guarantee
electrostatic-discharge (ESD) protection greater than
2000V per Method 3015.7
●● Guaranteed Low Charge Injection (5pC max)
These muxes operate with a single +2.7V to +16V supply
or with ±2.7V to ±8V dual supplies, while retaining CMOSlogic input compatibility and fast switching. The MAX396/
MAX397 are pin compatible with the industry standard
MAX306/MAX307, DG406/DG407, and DG506A/DG507A.
●● TTL/CMOS Compatible
●● Input Off-Leakage Current < 1nA at +85°C
●● Output Off-Leakage Current < 2.5nA at +85°C
●● Low Power Consumption < 10μW
Applications
●● Sample-and-Hold Circuits
●● Automatic Test Equipment
●● Avionics
●● Communications Systems
●● Battery-Operated Equipment ●● Audio Signal Routing
●● Low-Voltage Data Acquisition ●
● Industrial Process Control

Note 1: Signals on any terminal exceeding 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.

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).
Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges, i.e., VNO = 3V to 0V and 0V to -3V.
Note 6: Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.
Note 7: Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off-isolation = 20log VCOM/VNO, VCOM = output,
VNO = input to off switch.
Note 8: Leakage testing at single supply is guaranteed by correlation testing with dual supplies.

Applications Information
Overvoltage Protection
Operation with Supply Voltages
Other than ±5V
Using supply voltages less than ±5V reduces the analog
signal range. The MAX396/MAX397 multiplexers (muxes)
operate with ±3V to ±8V bipolar supplies or with a +3V to
+15V single supply. Connect V- to GND when operating with
a single supply. Both devices can also operate with unbalanced
supplies, such as +10V and -5V. The Typical Operating
Characteristics graphs show typical on-resistance with ±3V,
±5V, +3V, and +5V supplies.
These muxes operate with a single supply as low as
1V, although on-resistance and switching times become
extremely high. Performance is not guaranteed below
2.7V. This is useful information only because it assures
proper switch state while power supplies ramp up or
down slowly.
Proper power-supply sequencing is recommended for all
CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings 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 smallsignal 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 supply.
