MAX4601CAE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4601CAE is a quad, single-pole single-throw (SPST) CMOS analog switch featuring four normally closed 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 2.5Ω with a match and flatness of 0.5Ω over the signal range. Logic inputs are TTL/CMOS compatible with thresholds at 0.8V and 2.4V. It handles rail-to-rail analog signals with off-leakage current limited to 2.5nA max at +85°C. The component is housed in a 16-pin SSOP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'CAE' to confirm the 16-pin SSOP package and industrial-grade temperature range. Ensure compatibility with existing board layouts for surface-mount assembly. Confirm that the normally closed configuration aligns with the system's default state requirements before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a quad SPST switch with normally closed contacts is required. Verify that the 2.5Ω on-resistance meets the application's voltage drop constraints. Ensure the power supply range fits within the specified limits. Consider the 16-pin SSOP footprint during PCB design to ensure adequate clearance and thermal management.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4601/MAX4602/MAX4603 family of low-voltage CMOS analog switches. The MAX4601 variant specifically provides four normally closed switches, distinguishing it from the MAX4602 (normally open) and MAX4603 (mixed NC/NO). All variants share identical electrical characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes include the MAX4602CAE and MAX4603CAE, which share the same package and electrical specifications but differ in switch contact configuration. Other members of the MAX460x series may be considered if the specific NC/NO arrangement allows for circuit modification.
