MAX4663CAE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4663CAE+ is a quad single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 16-pin SSOP package. It operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. The device features a maximum on-resistance of 2.5Ω with guaranteed matching and flatness of 0.5Ω over the signal range. It supports rail-to-rail analog signals, offers >2kV ESD protection, and includes TTL/CMOS-compatible logic inputs via a separate VL pin. The component handles continuous currents up to 200mA and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed break-before-make switching for reliable signal routing
• Rail-to-rail signal handling capability across the full supply range
• Low on-resistance with tight channel matching and flatness specifications
• TTL/CMOS-compatible control inputs independent of analog supply voltage

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Audio-signal routing and PBX/PABX systems
• Data acquisition systems and ADC front-ends
• Sample-and-hold circuits and avionics applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'CAE+' confirms the commercial temperature range (0°C to +70°C) and SSOP-16 package configuration. Ensure the datasheet revision matches the required electrical characteristics. Confirm RoHS compliance status through official manufacturer documentation prior to integration into production designs.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when break-before-make timing is critical to prevent signal shorting between channels. Choose the CAE variant for commercial temperature environments requiring low on-resistance. Verify that the logic supply voltage (VL) aligns with the system's digital interface levels to ensure proper switching thresholds across the entire analog signal range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4661/MAX4662/MAX4663 family of quad SPST analog switches. Unlike the MAX4661 (all normally closed) and MAX4662 (all normally open), the MAX4663 integrates two normally closed and two normally open switches. This specific configuration enables controlled break-before-make operation, distinguishing it from the other family members which lack this guaranteed switching sequence.
