MAX4597EXK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4597EXK-T is a single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +2.0V to +5.5V supply and features a normally closed (NC) configuration. Key electrical parameters include a maximum on-resistance of 10 Ω, with a flatness of 1.5 Ω at +5V. The device offers fast switching times with tON max of 35ns and tOFF max of 40ns. It provides a -3dB bandwidth of 300MHz at +25°C and maintains an off-isolation of -80dB at 1MHz. Leakage currents are low at 0.5nA max, and charge injection is guaranteed at 5pC max. The component is housed in a 5-pin SC70 package and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix EXK-T corresponds to the 5-pin SC70 package variant when sourcing. Confirm that the NC (Normally Closed) state aligns with the circuit design requirements, as this differs from the NO variants in the same family. Ensure the supply voltage remains within the specified +2.0V to +5.5V range during operation to maintain parameter guarantees.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4597EXK-T when a normally closed default state is required for the analog switch path. Compare against the MAX4594EXK-T if a normally open state is needed instead, as they share identical pinouts and electrical characteristics otherwise. Consider the 6-pin µDFN variant only if board space constraints differ significantly from the SC70 footprint requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4594–MAX4597 series of low-voltage, single-supply SPST CMOS analog switches. The series is designed for portable applications requiring small footprints and low power consumption. The MAX4597 specifically denotes the Normally Closed configuration within this family, distinguishing it electrically from the Normally Open counterparts while sharing the same physical package and general performance metrics.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4594EXK-T is a direct pin-compatible alternative if a Normally Open (NO) state is acceptable. The MAX4595EXK-T serves as a replacement if a Normally Closed state is needed but a different manufacturer or minor parametric variation is permissible, though the MAX4594/5/6/7 family members are internally consistent.
