MAX4501CPA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4501CPA is a single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from +2V to +12V and features Rail-to-Rail signal handling capabilities. The device guarantees an on-resistance of 250Ω at +5V, with low off-leakage current of 1nA at +25°C and charge injection of 10pC. Switching speeds are specified as 75ns for turn-on and 50ns for turn-off. It utilizes TTL/CMOS-compatible logic thresholds and is housed in an 8-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic threshold behavior at higher supply voltages?

As the supply voltage increases toward +12V, the logic-level threshold rises slightly to approximately 3V, maintaining compatibility with CMOS outputs while exceeding the TTL high-level minimum.

How does the device handle signals exceeding the supply rails?

Internal reverse ESD-protection diodes clamp any analog signal that exceeds V+ or GND. Forward-diode current must be limited to the maximum current rating to prevent damage.

Are the COM, NO, and NC pins interchangeable?

Yes, the COM, NO, and NC pins are identical and interchangeable. Signals can pass equally well in either direction through these terminals.
