General Description
Maxim’s MAX312/MAX313/MAX314 analog switches
feature low on-resistance (10Ω max) and 1.5Ω on-resis-
tance matching between channels. These switches con-
duct equally well in either direction. They offer low
leakage over temperature (2.5nA at +85°C). Low power
consumption and ESD tolerance greater than 2000V per
Method 3015.7 are guaranteed.
The MAX312/MAX313/MAX314 are quad, single-
pole/single-throw (SPST) analog switches. The MAX312
is normally closed (NC), and the MAX313 is normally
open (NO). The MAX314 has two NC switches and two
NO switches. All three devices operate from a single
supply of +4.5V to +30V or from dual supplies of ±4.5V
to ±20V.

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- will be clamped by internal diodes. Limit forward diode current to
maximum current rating.
