MAX4666CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4666CPE+ is a quad single-pole single-throw (SPST) CMOS analog switch featuring a maximum on-resistance of 5Ω. It integrates two normally closed and two normally open switches to guarantee break-before-make switching times. The device operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies, with TTL/CMOS-compatible control inputs. Electrical characteristics include an off-leakage current of 5nA max at +85°C, turn-on time up to 275ns, and turn-off time up to 175ns. It is housed in a 16-pin Plastic DIP package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official datasheets to confirm pinout compatibility and electrical specifications before integration. Ensure that the operating voltage range matches the system requirements. Check for lead-free compliance if required by local regulations. Confirm the package type matches the PCB footprint design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise channel matching are critical. The guaranteed on-resistance flatness ensures consistent signal performance across the specified range. Consider the thermal dissipation limits based on the ambient temperature and power supply configuration.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4664/MAX4665/MAX4666 family of quad SPST analog switches. While the MAX4664 features four normally closed switches and the MAX4665 has four normally open switches, the MAX4666 uniquely combines two NC and two NO switches to provide break-before-make functionality.
