General Description

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.

Input Overvoltage and Undervoltage Clamping During undervoltage and overvoltage events, the internal diodes pull VDD/VSS supplies up/down. An advantage of this scheme is that the input impedance is high and currents do not flow though the MAX14756/MAX14757/ MAX14758 during overvoltage and undervoltage events.
