MAX4636ETB+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4636ETB+ is a dual single-pole double-throw (SPDT) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from 1.8V to 5.5V. The device features a maximum on-resistance of 4 ohms and a channel-to-channel matching of 100 milliohms. Switching times are specified at a maximum of 14ns for turn-on and 6ns for turn-off. Key electrical parameters include a charge injection of 2pC, off-state leakage current of 100pA, and -67dB crosstalk at 1MHz. It is housed in a 10-TDFN (3x3) package with an exposed pad.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Dual SPDT configuration providing two independent signal routing paths within a compact footprint.
• Low on-resistance characteristic ensuring minimal signal attenuation across the conduction path.
• Ultra-low charge injection capability designed to preserve signal integrity during switching transitions.
• CMOS technology enabling operation with low supply voltages while maintaining high isolation.

Analog Switches, Multiplexers, Demultiplexers Applications

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component status as End-of-Life (EOL) based on Product Change Notification dated October 18, 2019. Confirm RoHS3 compliance and MSL Level 1 classification before integration. Ensure the ordering suffix matches the required tape-and-reel packaging specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual SPDT switching is required with low on-resistance and fast switching speeds. Verify that the 1.8V to 5.5V single-supply range aligns with the system power architecture. Consider the 10-TDFN package dimensions for PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4635/MAX4636 family of CMOS analog switches. It shares functional similarities with other Maxim Integrated SPDT devices but is distinguished by its specific 4-ohm on-resistance and dual-channel configuration in a small TDFN package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed substitute part numbers include MAX4636ETB+T, MAX4636ETB+TG104, and MAX4636ETB-T. These variants share identical electrical characteristics and pinouts, differing primarily in packaging or manufacturing lot specifications.
