MAX4665ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4665ESE+T 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 provides rail-to-rail signal handling and maintains an on-resistance match between channels of 0.5Ω max. Off-leakage current is limited to 5nA max at +85°C. Digital inputs utilize +0.8V and +2.4V logic thresholds for TTL/CMOS compatibility. The component is housed in a 16-pin Narrow SO package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify that the ordering suffix matches the required temperature grade and packaging format. Confirm the specific pinout configuration aligns with the design requirements. Ensure compliance with RoHS directives as indicated by the plus sign in the part number. Cross-reference the manufacturer's latest documentation for any updates to the electrical characteristics or mechanical dimensions before finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration with low on-resistance is required. Verify that the supply voltage range meets the system's power constraints. Consider the thermal dissipation capabilities if high continuous currents are expected. Ensure the logic input levels are compatible with the controlling microcontroller or digital interface. Evaluate the package size against available board space.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4664/MAX4665/MAX4666 family of quad analog switches. The MAX4665 specifically features four normally open switches, distinguishing it from the MAX4664 which has four normally closed switches, and the MAX4666 which combines two normally open and two normally closed switches. All variants share similar electrical performance characteristics regarding on-resistance and leakage.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4664ESE+T and MAX4666ESE+T are direct functional replacements within the same package, differing only in switch state configuration. Other Maxim Integrated quad analog switches may require schematic modifications due to differences in pinouts or electrical parameters.
