MAX4502ESA

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4502ESA 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 from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix to confirm the package type and temperature grade before procurement. Ensure the component matches the required normally closed (NC) functionality, as the MAX4501 variant offers a normally open (NO) configuration. Confirm that the selected part number aligns with the intended operating environment and electrical requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4502ESA when a normally closed state is required upon power-up or logic low input. Consider the 250Ω on-resistance limit and 75ns switching speed against system timing constraints. Evaluate the -40°C to +85°C industrial temperature range suitability. Verify that the single-supply voltage range meets the application's power budget and signal swing requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4502ESA belongs to the MAX4501/MAX4502 family of low-voltage CMOS analog switches. This series provides compact solutions for signal routing in portable and battery-powered devices. The MAX4502 specifically complements the MAX4501 by offering a normally closed contact, allowing designers to implement fail-safe or default-closed circuit topologies within the same footprint and specification profile.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4501ESA serves as a functional substitute if a normally open (NO) configuration is acceptable instead of normally closed (NC). Other variants within the MAX4501/MAX4502 family may be considered based on package availability or extended temperature requirements.
