The MAX4501/MAX4502 are single-pole/single-throw (SPST), low-voltage, single-supply, CMOS analog switches. The MAX4501 is normally open (NO) while the MAX4502 is normally closed (NC). These devices operate continuously with a single supply between +2V and +12V and can handle rail-to-rail analog signals.
| Supply Voltage Range | +2V to +12V |
|---|---|
| On-Resistance (Typical) | 250 Ω at +5V |
| Off-Leakage Current (+25°C) | 1nA |
| Turn-On Time (Typical) | 75ns |
| Operating Temperature Range | -55°C to +125°C (MAX4501MJA) |
The MAX4501 is normally open (NO) while the MAX4502 is normally closed (NC).
The digital input has 0.8V and 2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility.
