MAX4663CAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4663CAE is a quad single-pole single-throw (SPST) CMOS analog switch featuring two normally open and two normally closed channels. It operates from a single +4.5V to +36V supply 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 handles rail-to-rail analog signals with off-leakage current limited to 5nA max at +85°C. The component includes guaranteed break-before-make switching and offers >2kV ESD protection. It is housed in a 16-pin SSOP package and functions within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Guaranteed break-before-make switching prevents signal overlap during channel transitions.
• Rail-to-Rail signal handling capability allows full voltage swing across the supply range.
• Low on-resistance ensures minimal signal attenuation in low-distortion applications.
• TTL/CMOS-compatible control inputs simplify interface with standard digital logic.

Analog Switches, Multiplexers, Demultiplexers Applications

• Reed relay replacement in automated test equipment
• ADC systems and data acquisition circuits
• Audio-signal routing and PBX/PABX systems

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CAE' corresponds to the commercial temperature range (0°C to +70°C) and 16-pin SSOP package configuration. Confirm that the ordering information matches the required channel configuration of two normally open and two normally closed switches. Ensure compatibility with the intended single or dual power supply voltages before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4663CAE when mixed normally open and normally closed switching is required within a single package. Compare on-resistance flatness and leakage specifications against alternative quad SPST switches if signal integrity is critical. Verify that the 16-pin SSOP footprint fits the available board space and that the commercial temperature range meets the operational environment requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4663CAE belongs to the MAX4661/MAX4662/MAX4663 family of quad analog switches manufactured by Analog Devices Inc./Maxim Integrated. While the MAX4661 features four normally closed switches and the MAX4662 features four normally open switches, the MAX4663 uniquely combines two of each type. This family is designed as a reliable, solid-state alternative to mechanical relays in applications requiring low power consumption and high reliability.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct substitutes include other members of the MAX466x family such as the MAX4661CAE or MAX4662CAE, provided the specific NO/NC channel configuration is acceptable for the design. Cross-referencing pinouts and electrical characteristics is essential when considering non-family replacements.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4663 and the MAX4661?

The MAX4663 contains two normally open and two normally closed switches, whereas the MAX4661 contains four normally closed switches. Both share similar electrical characteristics like on-resistance and supply ranges.

Does the MAX4663CAE support single-supply operation?

Yes, the device operates from a single +4.5V to +36V supply. For single-supply use, the V- pin should be connected to GND.

What is the significance of the 'break-before-make' feature in the MAX4663?

The break-before-make feature ensures that one switch opens before another closes, preventing momentary short circuits or signal overlap between channels during switching transitions.
