MAX4664CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4664CSE+ is a quad single-pole single-throw (SPST) CMOS analog switch featuring four normally closed channels. It operates from a single +4.5V to +36V supply or dual ±4.5V to ±20V supplies, with TTL/CMOS-compatible control inputs. The device guarantees a maximum on-resistance of 5Ω, matched between channels to 0.5Ω max and flatness over the signal range to 0.5Ω max. Off-leakage current is limited to 5nA max at +85°C. It handles rail-to-rail analog signals and offers ESD protection exceeding 2kV per Method 3015.7. The component is housed in a 16-pin Narrow SO package and functions within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range of 0°C to +70°C, distinct from the industrial 'E' variant. Confirm the '+'' suffix denotes lead-free compliance. Ensure the narrow SOIC-16 footprint matches the target PCB layout requirements before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when normally closed logic is required, as opposed to the MAX4665 which provides normally open switches. Consider the MAX4666 if break-before-make timing is necessary. Evaluate the 5Ω on-resistance against system loss budgets and verify that the 0°C to +70°C operating range meets environmental constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4664/MAX4665/MAX4666 family of quad analog switches manufactured by Analog Devices / Maxim Integrated. The series is designed to replace mechanical relays in applications demanding reliability and reduced board space. The MAX4664 specifically defines the normally closed configuration within this lineup.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the switches in the MAX4664?

The MAX4664 features four normally closed (NC) switches, meaning the connection between COM and NC is established when the logic input is low.

How does the on-resistance behave over the signal range?

The on-resistance is guaranteed to be flat, with a maximum variation of 0.5Ω over the specified signal range, ensuring consistent performance.

Is the MAX4664 compatible with standard logic families?

Yes, it has TTL/CMOS-compatible control inputs with +0.8V and +2.4V logic thresholds, allowing operation with ±15V supplies or a single +12V supply.
