MAX4609EPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4609EPE is a dual SPST CMOS analog switch in a 16-pin Plastic DIP package. It features a maximum on-resistance of 2.5Ω with guaranteed matching and flatness of 0.5Ω max. The device handles rail-to-rail signals using single (+4.5V to +36V) or dual (±4.5V to ±20V) supplies. Electrical characteristics include turn-on time of 110ns, turn-off time of 150ns, charge injection of 45pC, and off-leakage current of 30nA max at operating temperatures ranging from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as discontinued through official manufacturer channels before procurement planning. Confirm lead-free/RoHS compliance by checking for the '+' suffix in the ordering information. Ensure that the specific EPE variant matches the required temperature range and package dimensions for the target application design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when low distortion and precise resistance matching are critical. The MAX4609 provides mixed NO/NC functionality within a single package. Verify that the supply voltage requirements align with the system's available power rails. Consider the thermal derating specifications if continuous high-current operation is expected in the design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4607/MAX4608/MAX4609 family of dual analog switches. While the MAX4607 offers two NC switches and the MAX4608 provides two NO switches, the MAX4609 uniquely combines one of each type. All variants share identical electrical performance metrics regarding on-resistance and switching speeds.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements within the same series include the MAX4607EPE and MAX4608EPE. These alternatives offer different switch configurations but maintain the same 2.5Ω on-resistance and 16-PDIP footprint. Verify functional requirements against the specific NO/NC arrangement needed.
