MAX4665EPE is listed in the Analog Switches, Multiplexers, Demultiplexers range at ChipApex. The manufacturer field lists Analog Devices Inc./Maxim Integrated. Its product description is IC SWITCH SPST-NO X 4 4OHM 16DIP. Review the specifications below when checking this part for your BOM.
The MAX4665EPE is a quad single-pole single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 5Ω. It operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies. The device handles Rail-to-Rail analog signals with an off-leakage current of 5nA maximum at +85°C. On-resistance is matched between channels to 0.5Ω maximum and remains flat over the specified signal range. It includes TTL/CMOS-compatible control inputs and guarantees greater than 2kV ESD protection per Method 3015.7.
Verify the specific suffix 'EPE' confirms the -40°C to +85°C extended temperature range and 16-pin Plastic DIP package. Confirm RoHS compliance status for the exact revision, as older Maxim Integrated batches may vary. Ensure the source document matches the Analog Devices / Maxim Integrated datasheet for accurate pinout and electrical specifications.
Select this component when a quad SPST switch with guaranteed on-resistance matching is required. It serves as a direct alternative to mechanical relays in applications demanding lower board space and higher reliability. Verify that the 5Ω on-resistance meets the system's voltage drop requirements under load conditions.
This part belongs to the MAX4664/MAX4665/MAX4666 family of 5Ω quad analog switches. The MAX4665 specifically provides four normally open switches, distinguishing it from the MAX4664 (normally closed) and MAX4666 (mixed break-before-make). All variants share identical electrical characteristics and packaging options.
Public confirmed substitute part numbers are not available in the provided documentation.
