MAX4502CSA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4502CSA is a single-pole/single-throw (SPST), low-voltage, single-supply CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally closed (NC) configuration and operates continuously with a single supply between +2V and +12V. The device handles Rail-to-Rail analog signals with an off-leakage current of 1nA at +25°C or 10nA at +85°C. Digital inputs utilize 0.8V and 2.4V logic thresholds for TTL/CMOS compatibility at +5V. Electrical characteristics include a maximum on-resistance of 250Ω at +5V, turn-on time of 75ns, and turn-off time of 50ns. It is housed in an 8-pin SO package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CSA against official documentation to confirm the 8-pin SO package and commercial temperature range. Ensure the ordering information matches the manufacturer's current catalog to avoid discrepancies in lead times or availability status. Cross-reference the part number with authorized distributors to confirm authenticity and compliance with RoHS standards before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4502CSA when a normally closed state is required upon power-up or reset. Compare its 250Ω on-resistance and switching speeds against other series members like the MAX4501 if an open default state is preferred. Consider the 8-pin SO package constraints regarding thermal dissipation and board space relative to smaller packages like SOT23-5 or SC70-5 available in the same family.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4502CSA belongs to the MAX4501/MAX4502 family of low-voltage CMOS analog switches. While the MAX4501 offers a normally open configuration, the MAX4502 provides a normally closed path. Both share identical electrical specifications and pinouts, differing only in their default switch states. This family is designed for portable and battery-powered applications requiring efficient signal management.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4501CSA serves as a functional substitute if a normally open configuration is acceptable instead of normally closed. Other variants within the MAX4501/MAX4502 series may be considered if different temperature ranges or packaging options are required, provided the electrical parameters remain compatible with the design.
