MAX4603EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4603EPE+ is a quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin Plastic DIP package. It integrates two normally closed and two normally open switches, offering a maximum on-resistance of 2.5Ω with guaranteed matching of 0.5Ω and flatness of 0.5Ω over the signal range. The device supports single supplies from +4.5V to +36V or dual supplies from ±4.5V to ±20V. Key electrical parameters include an off-leakage current of 0.5nA maximum at +85°C, turn-on time of 160ns, and turn-off time of 170ns. It operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm the specific EPE+ suffix corresponds to the 16-pin PDIP package and industrial temperature grade. Ensure supply chain documentation matches the manufacturer's ordering information for compliance and traceability requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when mixed normally open and normally closed configurations are required within a single package. Compare against the MAX4601 (all NC) and MAX4602 (all NO) if uniform switch states suffice. Evaluate power supply constraints to ensure compatibility with the specified single or dual voltage ranges before integration.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4601/MAX4602/MAX4603 family of 2.5Ω quad SPST CMOS analog switches. While sharing identical electrical performance characteristics, the MAX4603 specifically combines two normally closed and two normally open switches, providing design flexibility compared to the uniform configurations of its siblings.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same package include the MAX4601EPE+ and MAX4602EPE+. Verify that the application circuit can accommodate the different switch states (NC vs. NO) inherent to these alternative part numbers.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the specific switch configuration of the MAX4603?

The MAX4603 contains four independent SPST switches: two are configured as normally closed (NC) and two are configured as normally open (NO).

How does the on-resistance behave over the signal range?

The on-resistance is guaranteed to be flat with a maximum variation of 0.5Ω over the specified analog signal range.

Is the device compatible with standard logic families?

Yes, the digital inputs have TTL/CMOS-compatible thresholds (+0.8V and +2.4V), ensuring compatibility with standard logic levels when using appropriate supply voltages.
