Precision, 16-Channel/Dual 8-Channel,
Low-Voltage, CMOS Analog Multiplexers
_______________General Description
The MAX396/MAX397 low-voltage, CMOS analog multi-
plexers (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 (transi-
tion 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 low-
voltage 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 sup-
ply 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 industry-
standard 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 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., V

Note 6:
Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25°C.

Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off-isolation = 20log V

Note 8:
Leakage testing at single supply is guaranteed by correlation testing with dual supplies.
