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 1W--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 2
max channel-to-channel matching, 30
max on-resistance (R
ON
), and 4
max R
ON
flatness
over the specified range.
These switches are also fully specified for single +5V
operation, with 2
max R
ON
match, 60
max R
ON, and
6
max flatness.
These low-voltage switches also offer 5pC max charge
injection, and ESD protection is greater than 2000V, per
method 3015.7.

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 1:
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.
