MAX4663CAE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4663CAE+T is a quad single-pole single-throw (SPST) CMOS analog switch in a 16-pin SSOP package. It features a maximum on-resistance of 2.5Ω with guaranteed matching and flatness of 0.5Ω over the signal range. The device supports rail-to-rail analog signals, operates from +4.5V to +36V single supplies or ±4.5V to ±20V dual supplies, and includes TTL/CMOS-compatible logic inputs. It provides guaranteed break-before-make switching, >2kV ESD protection, and low off-leakage current of 5nA max at +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix 'AE' confirms the 16-lead shrink small-outline package (SSOP). Confirm the 'C' designation indicates the commercial temperature range of 0°C to +70°C. Ensure the '+T' suffix matches the required tape-and-reel packaging format for surface-mount assembly processes.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when break-before-make timing is critical to avoid shorting signals. Verify that the 2.5Ω on-resistance meets the distortion requirements for the specific analog signal path. Ensure the operating environment remains within the commercial temperature limits defined by the 'C' grade.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4661/MAX4662/MAX4663 family of quad SPST switches. Unlike the MAX4661 (all NC) or MAX4662 (all NO), the MAX4663 integrates two normally closed and two normally open switches. This configuration distinguishes it within the series while sharing identical electrical performance characteristics.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the maximum on-resistance flatness specified for this device?

The on-resistance is guaranteed to be flat within 0.5Ω max over the entire specified signal range.

How does the MAX4663 differ from the MAX4661 and MAX4662?

The MAX4663 contains two normally closed and two normally open switches, whereas the MAX4661 has four normally closed and the MAX4662 has four normally open switches.

Is the logic input compatible with standard logic families?

Yes, the separate logic supply pin guarantees TTL and CMOS logic compatibility across the entire supply voltage range.
