This file introduces the MAX4514/MAX4515, which are single-pole/single-throw (SPST), CMOS, low-voltage, single-supply analog switches with very low switch on-resistance. MAX4514 is normally open (NO). MAX4515 is nor- mally closed (NC). These CMOS switches can operate continuously with a single supply between +2V and +12V. 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. All digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a +5V supply. For pin-compatible parts for use with dual supplies, see the MAX4516/MAX4517.
The MAX4514 and MAX4515 are single‑pole/single‑throw (SPST) CMOS analog switches that operate from a single supply voltage of +2 V to +12 V. They feature very low on‑resistance (20 Ω at +5 V, 10 Ω at +12 V) and ultra‑low leakage currents (1 nA off‑leakage at +25 °C, 2 nA on‑leakage at +25 °C). The devices are available in SOT23‑5, DIP‑8 and SO‑8 packages and are TTL/CMOS‑logic compatible.
Key performance parameters include a turn‑on time of 150 ns, turn‑off time of 100 ns, charge injection of 10 pC, and high‑frequency operation up to 250 MHz in 50 Ω systems. The data sheet provides detailed pin configurations, absolute maximum ratings, electrical characteristics, and recommended application circuits.

They operate with a single supply voltage between +2 V and +12 V.
The typical on‑resistance is 20 Ω when powered at +5 V.
The off‑leakage current is only 1 nA at +25 °C.
Yes, the digital inputs have thresholds of 0.8 V to 2.4 V, making them TTL/CMOS compatible.
