MAX4502EXK+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4502EXK+T 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 and offers guaranteed on-resistance of 250Ω at +5V. Key electrical parameters include off-leakage current of 1nA at +25°C and 10nA at +85°C, on-leakage current of 2nA at +25°C, and charge injection of 10pC. Switching speeds are specified as tON = 75ns and tOFF = 50ns. It is housed in a SC70-5 package and supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EXK+T confirms the SC70-5 package and industrial temperature grade (-40°C to +85°C). Ensure compliance with RoHS directives if required by the application. Cross-reference the manufacturer's latest documentation for any updates to pin configurations or absolute maximum ratings before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4502EXK+T when a normally closed state is required upon power-up or reset. Compare its 250Ω on-resistance against other series variants if lower resistance is critical for high-current applications. Consider the SC70-5 package dimensions for space-constrained PCB layouts. Verify that the 1nA off-leakage specification meets the requirements for high-impedance signal paths.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4501/MAX4502 family of low-voltage CMOS analog switches. The MAX4502 variant specifically provides a normally closed contact, contrasting with the MAX4501's normally open design. Both share identical electrical characteristics and packaging options, differing primarily in their default switch state and internal logic inversion.
