General Description
Maxim's MAX312L/MAX313L/MAX314L analog switch-
es feature low on-resistance (10
max) and 1.5 on-
resistance matching between channels. These switches
are +3V logic compatible when powered from 15V or
+12V supplies. The switches conduct equally well in
either direction, and offer low leakage over temperature
(2.5nA at +85C).
The MAX312L/MAX313L/MAX314L are quad, single-
pole/single-throw (SPST) analog switches. The MAX312L
is normally closed (NC), and the MAX313L is normally
open (NO). The MAX314L has two NC switches and two
NO switches. All three devices operate from a single
+4.5V to +36V supply or from dual 4.5V to 20V, and
are available in 16-pin TSSOP, SO, and DIP packages.

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.
