MAX4663EWE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4663EWE+ is a quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin Wide SOIC package. It operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies, featuring TTL/CMOS-compatible logic inputs. The device provides a maximum on-resistance of 2.5Ω with guaranteed matching and flatness of 0.5Ω over the signal range. It handles rail-to-rail analog signals and includes two normally closed and two normally open switches with guaranteed break-before-make switching. Operating temperature ranges from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Features low on-resistance of 2.5Ω max with guaranteed channel matching and flatness for low-distortion performance.
• Handles full rail-to-rail analog signal swings across the specified operating voltage range.
• Includes guaranteed break-before-make switching to prevent signal shorting during transitions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and electrical specifications before integration. Ensure that the Wide SOIC package dimensions align with the target PCB footprint. Check for RoHS compliance status if required by specific manufacturing standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise signal routing are critical. The MAX4663 variant is specifically chosen for its mixed normally open and normally closed configuration. Verify that the system power supply falls within the specified single or dual voltage limits to ensure proper operation.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4661/MAX4662/MAX4663 family of quad analog switches. While sharing similar electrical characteristics and packages, the MAX4663 is distinct due to its specific combination of two normally closed and two normally open switches, unlike the all-NC MAX4661 or all-NO MAX4662.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4663 and other members of the MAX466x family?

The MAX4663 features two normally closed (NC) and two normally open (NO) switches, whereas the MAX4661 has four NC switches and the MAX4662 has four NO switches.

Does the MAX4663 support break-before-make switching?

Yes, the MAX4663 guarantees break-before-make switching, which prevents the common terminal from connecting to both the NO and NC terminals simultaneously during state transitions.
