MAX4677EUE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4677EUE+ is a quad single-pole single-throw (SPST) CMOS analog switch in a 16-pin TSSOP package. It operates from a single +2.7V to +11V or dual ±2.7V to ±5.5V supply. The device features a maximum on-resistance of 1.6Ω at ±5V, with channel matching of 0.3Ω and flatness of 0.4Ω. It supports rail-to-rail analog signals and includes a separate logic supply input (VL). Key electrical parameters include 0.1nA off-leakage current, -84dB crosstalk at 1MHz, and a -3dB bandwidth of 66MHz. Turn-on time is 350ns and turn-off time is 150ns at ±5V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component against official Analog Devices datasheets to confirm pinout and electrical specifications. Ensure the operating voltage range matches the system requirements. Check for RoHS compliance status if required by local regulations. Confirm the package type is suitable for the intended PCB layout.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise signal switching are required. The separate logic supply allows compatibility with various digital logic levels. Consider the thermal dissipation limits in the TSSOP package for high-current applications. Verify that the single-supply or dual-supply configuration fits the design constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4677/MAX4678/MAX4679 family of quad analog switches. The MAX4677 specifically provides four normally closed switches, distinguishing it from the MAX4678 (normally open) and MAX4679 (mixed NC/NO with break-before-make). All variants share similar electrical characteristics and packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include the MAX4678EUE+ and MAX4679EUE+. These parts share the same package and general electrical performance but differ in switch state configuration. Verify logic input polarity and switch behavior before substitution.
