MAX4609CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4609CPE is a dual SPST CMOS analog switch in a 16-pin Plastic DIP package. It features a maximum on-resistance of 2.5Ω, matched between channels to 0.5Ω max and flatness of 0.5Ω max over the signal range. The device handles rail-to-rail analog signals with off-leakage current of 2.5nA max at +85°C. It operates from single supplies of +4.5V to +36V or dual supplies of ±4.5V to ±20V. Logic inputs have +0.8V and +2.4V thresholds for TTL/CMOS compatibility. Turn-on time is 110ns and turn-off time is 150ns.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as discontinued based on distributor records. Confirm RoHS compliance through the '+' suffix designation. Ensure the specific package type matches the required PCB footprint. Check for lead-free certification documentation if environmental regulations apply to the assembly process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when low distortion and high reliability are required compared to mechanical relays. Verify that the supply voltage range fits the system design. Consider the 16-pin PDIP package constraints. Evaluate the 2.5Ω on-resistance against the load requirements. Ensure logic levels match the control interface.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4609CPE belongs to the MAX4607/MAX4608/MAX4609 family of dual analog switches. It differs from the MAX4607 (two NC switches) and MAX4608 (two NO switches) by providing one normally closed and one normally open switch. All variants share identical electrical characteristics and pin configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4607CPE and MAX4608CPE are pin-compatible alternatives within the same family. Verify the switch configuration (NC/NO) matches the circuit requirements before substitution.
