MAX14758
General Description
Quad SPST +70V Analog Switches
The MAX14756/MAX14757/MAX14758 are analog
switches with a low on-resistance of 10Ω (max) that
conduct equally well in both directions. All devices have a
rail-to-rail analog-signal range. They operate with a single
+10V to +70V supply in unipolar applications or ±35V dual
supplies in bipolar applications. The bipolar supplies can
be offset and do not have to be symmetrical.
The MAX14756 is a quad normally closed (NC) single-
pole/single-throw (SPST) switch, the MAX14757 is a quad
normally open (NO) SPST switch, and the MAX14758 has
two NO and two NC SPST switches. These switches have
5Ω (typ) on-resistances and low on-leakage currents of
0.01nA (typ). The on-resistance flatness is 0.004Ω (typ).
The devices are suitable for a multitude of analog signal
routing and switching applications. They are specified over
an extended temperature range of -40°C to +85°C, but can
be operated up to +125°C with elevated leakage currents.

Note 1:
Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer
board. For detailed information on package thermal considerations, refer to
www.maximintegrated.com/thermal-tutorial.
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.
