MAX4663CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4663CPE is a quad SPST CMOS analog switch featuring two normally open and two normally closed channels. It operates from single +4.5V to +36V or dual ±4.5V to ±20V supplies with TTL/CMOS-compatible logic inputs. The device guarantees a maximum on-resistance of 2.5Ω, matched between channels to 0.5Ω max, and flatness of 0.5Ω max over the signal range. It supports rail-to-rail analog signals, offers >2kV ESD protection, and includes guaranteed break-before-make switching. Operating temperature ranges from 0°C to +70°C in a 16-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Rail-to-Rail signal handling capability across the full supply voltage range
• Low on-resistance with tight matching and flatness specifications for low-distortion performance
• TTL/CMOS-compatible control inputs ensure logic compatibility across all operating voltages

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• Avionics and communication systems requiring reliable signal routing
• Data acquisition and sample-and-hold circuits
• Audio-signal routing and PBX/PABX systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) rather than the extended industrial range. Confirm the 'P' suffix corresponds to the 16-pin Plastic DIP package format required for your assembly process. Ensure the ordering code matches the exact quad SPST configuration with mixed NO/NC channels defined for this part number.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when break-before-make timing is critical to avoid signal overlap between channels. Choose this part over MAX4661 or MAX4662 variants if the design requires a mix of normally open and normally closed switches within a single package. Verify that the 2.5Ω on-resistance meets the voltage drop requirements for your specific load currents.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4661/MAX4662/MAX4663 family of quad analog switches manufactured by Analog Devices Inc./Maxim Integrated. While the MAX4661 provides four normally closed switches and the MAX4662 provides four normally open switches, the MAX4663 uniquely combines two of each type. All three share identical electrical characteristics regarding resistance, leakage, and power supply operation.
