MAX4605CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4605CSE+ is a quad, single-pole single-throw (SPST) CMOS analog switch featuring four normally open channels. It operates from a single supply of +4.5V to +36V or dual supplies of ±4.5V to ±20V. The device guarantees a maximum on-resistance of 5Ω with a channel-to-channel match of 0.5Ω and flatness of 0.5Ω over the signal range. Logic inputs are TTL/CMOS compatible, requiring thresholds of +0.8V for low and +2.4V for high. Electrical characteristics include a maximum turn-on time of 120ns, turn-off time of 130ns, off-leakage current of 0.5nA at +85°C, and charge injection of 225pC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation against official Analog Devices documentation to confirm the specific package type and temperature grade. Ensure that the ordering suffix aligns with the required operating conditions and physical footprint specifications before finalizing procurement decisions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST configuration with normally open contacts is required. Verify that the application demands a maximum on-resistance of 5Ω and can accommodate the specified power supply ranges. Confirm that the 16-pin Narrow SOIC package fits the board layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4604/MAX4605/MAX4606 family of quad CMOS analog switches. While the MAX4604 provides normally closed switches and the MAX4606 offers a mixed configuration, the MAX4605 specifically provides four normally open switches. All variants share identical electrical performance metrics regarding resistance, leakage, and speed.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible alternatives within the same family include the MAX4604CSE+ and MAX4606CSE+. Note that these parts differ in contact state configuration rather than electrical parameters.
