Precision, 16-Channel/Dual 8-Channel,
Low-Voltage, CMOS Analog Multiplexers
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.
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
These muxes operate with a single +2.7V to +16V supply or with ±2.7V to ±8V dual supplies, while retaining
CMOS-logic input compatibility and fast switching. The
MAX396/MAX397 are pin compatible with the industrystandard MAX306/MAX307, DG406/DG407, and
DG506A/DG507A.

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
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 onresistance with ±3V, ±5V, +3V, and +5V supplies.
(Switching times increase by a factor of two or more for
operation at 5V or below.)
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.
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 supply.

Overvoltage Protection
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
