MAX4678EPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4678EPE+ is a quad single-pole single-throw (SPST) CMOS analog switch housed in a 16-pin plastic DIP package. It features four normally open switches with a maximum on-resistance of 2Ω across the operating temperature range and 1.6Ω at +25°C. The device supports dual supplies from ±2.7V to ±5.5V or a single supply from +2.7V to +11V, accommodating rail-to-rail analog signals. Key electrical parameters include a maximum off-leakage current of 10nA, a -3dB bandwidth of 66MHz, and crosstalk of -84dB at 1MHz. Operating temperatures range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity by checking manufacturer markings against official datasheet specifications. Confirm the 16-pin DIP package configuration matches design requirements. Ensure the ordering suffix corresponds to the standard RoHS-compliant version. Validate that the specific batch meets the required temperature grade for the intended operational environment.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when low distortion and precise channel matching are critical. The separate logic supply allows flexible interface compatibility with various digital logic families. Consider the thermal derating characteristics if operating near the upper temperature limit. Verify that the package footprint aligns with existing PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4677/MAX4678/MAX4679 family of quad analog switches. The MAX4678 specifically provides four normally open channels, distinguishing it from the MAX4677 which offers normally closed switches. Both share identical pinouts and electrical characteristics, facilitating direct substitution based on contact state requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

MAX4677EPE+ serves as a functional substitute offering identical electrical performance but with normally closed switch contacts instead of normally open.
