MAX4661EAE-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4661EAE-T is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features four independent switches with a maximum on-resistance of 2.5Ω and guaranteed matching to 0.5Ω. The device operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies, with TTL/CMOS-compatible logic inputs. It handles rail-to-rail analog signals and offers low off-leakage current of 5nA max at +85°C. The component is housed in a 16-pin SSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Ensure the source provides valid RoHS compliance status and traceability records. Confirm that the supplier is authorized to distribute Maxim Integrated products to guarantee authenticity and proper storage conditions during transit.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when low distortion and high reliability are required over mechanical relays. The MAX4661 specifically provides normally closed switches, distinguishing it from the MAX4662 (normally open) and MAX4663 (mixed). Ensure the application voltage stays within the specified single or dual supply ranges to maintain performance specifications.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4661/MAX4662/MAX4663 family of quad SPST CMOS analog switches. These devices are designed as solid-state alternatives to electromechanical relays, offering lower power consumption and smaller board space. The family shares similar electrical characteristics but differs in switch configuration and break-before-make timing.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4662EAE-T (normally open) and MAX4663EAE-T (mixed NC/NO with break-before-make). Verify pin compatibility and logic polarity differences before substitution.
