MAX312/MAX313/MAX314 10Ω, Quad, SPST, CMOS Analog Switches are switch model, with low resistance and high ESD tolerance, provide four switches, can work in single power supply or dual power supply
The Maxim MAX312, MAX313, and MAX314 are quad single‑pole/single‑throw (SPST) CMOS analog switches. MAX312 is normally closed, MAX313 normally open, and MAX314 combines two NC and two NO switches. All devices operate from a single supply of +4.5 V to +30 V or dual supplies of +4.5 V to +20 V and offer low on‑resistance, low leakage, and high ESD tolerance.
These switches are suited for test equipment, communication systems, audio signal routing, avionics, sample‑and‑hold circuits, and data‑acquisition systems. The datasheet provides absolute maximum ratings, electrical characteristics for both dual‑ and single‑supply operation, typical performance graphs, pin configurations, and detailed package dimensions.
