Precision, Quad, SPST Analog Switches
_______________General Description
The MAX391/MAX392/MAX393 are precision, quad,
single-pole/single-throw (SPST) analog switches
designed to operate at +3V, +5V, or ±5V. The MAX391
has four normally closed (NC) switches, and the
MAX392 has four normally open (NO) switches. The
MAX393 has two NO and two NC switches. All three
devices offer low leakage (100pA max) and fast switch-
ing speeds (t
ON
≤
130ns, t
OFF
≤
75ns). Power con-
sumption is just 1µW—ideal for battery-operated equip-
ment. All devices operate from a single +3V to +15V
supply or from dual ±3.0V to ±8V supplies.
With ±5V supplies, the MAX391/MAX392/MAX393 offer
guaranteed 2Ω max channel-to-channel matching, 30Ω
max on-resistance (R
ON
), and 4Ω max R
ON
flatness
over the specified range.
These switches are also fully specified for single +5V
operation, with 2Ω max R
ON
match, 60Ω max R
ON, and
6Ω max flatness.
These low-voltage switches also offer 5pC max charge
injection, and ESD protection is greater than 2000V, per
method 3015.7.

Signals on NC_, NO_, COM_, or IN_ exceeding V+ or V- are clamped by internal diodes. Limit forward diode current to maxi-
mum 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.

Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal range.
Leakage parameters are 100% tested at maximum rated hot temperature and guaranteed by correlation at +25°C.
