The MAX4664, MAX4665, and MAX4666 are quad analog switches with low on‑resistance and rail‑to‑rail signal handling. The MAX4664 offers four normally closed switches, the MAX4665 four normally open switches, and the MAX4666 a mix of two NC and two NO switches with break‑before‑make timing.
The datasheet details absolute maximum ratings, electrical characteristics for both single‑ and dual‑supply operation, typical performance graphs, pin configurations, ordering information, and recommended application circuits such as over‑voltage protection and charge‑injection testing.
| On‑resistance (max) | 5 Ω |
|---|---|
| On‑resistance match (max) | 0.5 Ω |
| Off‑leakage current (max at +85 °C) | 5 nA |
| Single‑supply voltage range | +4.5 V to +36 V |
| Dual‑supply voltage range | ±4.5 V to ±20 V |
| Operating temperature range (E‑grade) | -40 °C to +85 °C |
The maximum on‑resistance is 5 Ω.
They can operate from a single supply of +4.5 V to +36 V or from dual supplies of ±4.5 V to ±20 V.
The off‑leakage current is limited to 5 nA max at +85 °C.
