MAX4515CUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4515CUK-T is a single-pole/single-throw (SPST), CMOS, low-voltage analog switch housed in a SOT23-5 package. It operates on a single supply between +2V and +12V and handles rail-to-rail analog signals. The device features normally closed contacts with a maximum on-resistance of 20Ω at +5V and 10Ω at +12V. Key electrical parameters include an off-leakage current of 1nA at +25°C, charge injection of 10pC, and switching speeds of tON = 150ns and tOFF = 100ns. It supports TTL/CMOS logic compatibility and operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CUK' corresponds to the commercial temperature range (0°C to +70°C) and SOT23-5 packaging as documented in official ordering tables. Confirm that the '+T' designation indicates tape-and-reel delivery format. Ensure the component source matches Analog Devices or Maxim Integrated specifications to guarantee performance alignment with datasheet limits.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when a normally closed state is required upon power-up or input deactivation. Verify that the single-supply voltage range (+2V to +12V) aligns with system rails. Consider the 20Ω on-resistance limit for signal loss calculations. Ensure the digital control logic levels are compatible with the V+ supply voltage to maintain proper switching thresholds.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4514/MAX4515 family of low-voltage, low-on-resistance CMOS analog switches. The MAX4515 variant specifically provides a normally closed contact, contrasting with the MAX4514's normally open configuration. Both share identical pinouts and electrical characteristics, allowing for design flexibility based on default switch states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4514CUK-T serves as a functional substitute if a normally open state is acceptable instead of normally closed. For dual-supply applications requiring similar form factors, the MAX4516/MAX4517 series offers pin-compatible alternatives.
