MAX4609CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4609CPE+ is a dual single-pole single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 2.5Ω. It contains one normally open and one normally closed channel, operating from single supplies of +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device ensures low distortion with matched on-resistance of 0.5Ω max and flatness of 0.5Ω max over the signal range. Off-leakage current is limited to 2.5nA max at +85°C. It operates within a commercial temperature range of 0°C to +70°C and is housed in a 16-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix matches the required specifications. The '+' suffix indicates a lead-free and RoHS-compliant package. Confirm the 'C' suffix corresponds to the commercial temperature range of 0°C to +70°C. Ensure the 'PE' suffix aligns with the 16-pin Plastic DIP package requirement. Cross-reference the manufacturer's official documentation to confirm availability and specific lot codes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mixed normally open/normally closed dual switch topology is required. Verify that the supply voltage range fits the system design, as it supports both single and dual rails. Check that the 2.5Ω on-resistance meets the signal integrity requirements. Ensure the 0°C to +70°C temperature range is sufficient for the intended environment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4607/MAX4608/MAX4609 family of dual analog switches. While sharing identical electrical characteristics and pinouts, the MAX4609 is distinct due to its mixed switch configuration. The MAX4607 offers two normally closed switches, whereas the MAX4608 provides two normally open switches. All variants utilize the same BiCMOS process technology.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes include the MAX4607CPE+ and MAX4608CPE+. Note that these parts differ in switch state configuration: MAX4607CPE+ has two normally closed switches, and MAX4608CPE+ has two normally open switches. Verify circuit logic compatibility before substitution.
