The MAX4516/MAX4517 are low-voltage, dual-supply, single-pole/single-throw (SPST) CMOS analog switches with very low switch on-resistance. The MAX4516 is normally open (NO). The MAX4517 is normally closed (NC). These CMOS switches can operate continuously with dual supplies between ±1V and ±6V. Each switch can handle rail-to-rail analog signals. The off-leakage cur- rent maximum is only 1nA at +25°C or 20nA at +85°C. The digital input is referenced to the positive power supply and is CMOS compatible. For pin-compatible parts for use with a single supply, refer to the MAX4514/MAX415.
The MAX4516 (normally open) and MAX4517 (normally closed) are single‑pole/single‑throw CMOS analog switches that operate with dual supplies from ±1 V to ±6 V. They handle rail‑to‑rail analog signals and feature very low on‑resistance and off‑leakage currents, making them suitable for battery‑operated equipment, audio/video routing, low‑voltage data‑acquisition, communications, PCMCIA cards, cellular phones and modems.
The datasheet provides absolute maximum ratings, electrical characteristics, typical operating curves, pin descriptions, package options (SOT23‑5, DIP‑8, SO‑8, etc.), and test circuit diagrams. It also includes ordering information and mechanical dimensions for each package.
