MAX4515CSA+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4515CSA+ is a single-pole/single-throw (SPST), CMOS, low-voltage analog switch with very low on-resistance. It operates continuously with a single supply between +2V and +12V and handles rail-to-rail analog signals. The device features normally closed (NC) contacts, ensuring the switch is closed when the input is low. It offers guaranteed on-resistance of 20Ω at +5V and 10Ω at +12V supplies. Off-leakage current is limited to 1nA at +25°C and 20nA at +85°C. The component supports fast switching speeds with turn-on times up to 150ns and turn-off times up to 100ns. It utilizes TTL/CMOS-compatible logic thresholds for +5V operation.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the ordering suffix CSA indicates an 8-pin SO package with a commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status through official manufacturer documentation or authorized distributors. Ensure the specific lot code matches project requirements for traceability. Cross-reference the datasheet revision date to validate parameter accuracy against current production standards.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part for applications requiring a normally closed SPST switch in a small surface-mount footprint. Compare on-resistance flatness and leakage currents against system signal integrity requirements. Consider the break-before-make timing characteristics if sequential switching is necessary. Evaluate thermal dissipation limits within the SO package constraints for high-duty-cycle operations.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4514/MAX4515 family of low-voltage analog switches. The MAX4514 variant provides a normally open (NO) configuration, while the MAX4515 provides a normally closed (NC) function. Both share identical pinouts and electrical characteristics, allowing for design flexibility based on default state requirements without changing the physical layout.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4514CSA+ serves as a functional substitute if a normally open configuration is acceptable. Verify that any replacement maintains the same 8-pin SO package dimensions and pinout compatibility. Ensure the alternative device meets the required +2V to +12V operating voltage range and logic threshold specifications.
