MAX4595DCKR

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4595DCKR is a single-channel, normally-closed analog switch manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.4 V to 5.5 V and is housed in a compact SC-70-5 surface-mount package. The device features a maximum on-resistance of 10 Ohms and supports a DC switch current of 100 mA. Electrical performance includes a -3dB bandwidth of 300 MHz, charge injection of 2 pC, and leakage current of 500 pA. Switching times are specified at a maximum of 35 ns for turn-on and 40 ns for turn-off. The component functions within an ambient temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Audio signal path switching
• Instrumentation front-end multiplexing

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix DCKR against the manufacturer datasheet to confirm the SC-70-5 package and tape-and-reel quantity. Ensure the ordering information matches the required normally-closed configuration, as other variants in the series may offer different states. Cross-reference the RoHS status and moisture sensitivity level with current environmental compliance requirements before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally-closed state is required upon power-up or control deactivation. Compare the 10 Ohm on-resistance against system loss budgets. Verify that the 2.4 V minimum supply voltage aligns with the available rail. Consider the 300 MHz bandwidth if high-frequency signal integrity is critical for the application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX459x family of single-pole single-throw (SPST) analog switches. It shares the same pinout and package dimensions with the MAX4594, which differs primarily by being a normally-open device. The DCKR suffix specifically denotes the SC-70-5 package type used in this variant.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4594DCKR serves as a functional substitute if a normally-open configuration is acceptable instead of normally-closed. Other SPST switches in the SC-70-5 package may be considered if electrical parameters such as on-resistance and bandwidth meet the design specifications.
