MAX351CSE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX351CSE+T is a precision, quad, single-pole single-throw (SPST) analog switch featuring four normally closed channels. It operates with a single positive supply (+10V to +30V) or split supplies (±4.5V to ±20V). The device offers low on resistance of less than 35Ω, guaranteed to match within 2Ω between channels and remain flat over the analog signal range (∆3Ω max). Leakage is less than 250pA at +25°C and less than 6nA at +85°C. Switching times include turn-on time less than 175ns and turn-off time less than 145ns. It utilizes CMOS logic inputs for reduced loading and provides electrostatic discharge protection greater than 2000V.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component authenticity by checking the manufacturer markings against official datasheet specifications. Confirm the package type matches the narrow SOIC-16 format required for your design. Ensure the temperature grade corresponds to the 'C' suffix for commercial range applications. Cross-reference the ordering information to validate the specific part number configuration before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when precise analog signal routing is required with minimal distortion. The low on-resistance and flatness characteristics make it suitable for high-fidelity signal paths. Consider the supply voltage requirements, as the device supports both unipolar and bipolar configurations. Evaluate the thermal dissipation capabilities if operating near maximum ratings in enclosed environments.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX351 belongs to a family of precision analog switches that includes the MAX352 and MAX353. While the MAX351 features four normally closed switches, the MAX352 provides four normally open switches, and the MAX353 combines two of each. All variants share identical electrical performance metrics and fabrication processes, differing only in their internal switch states.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional replacements within the same family include the MAX352CSE+T and MAX353CSE+T, provided the switch state (NO vs NC) aligns with circuit requirements. Other packages such as the MAX351ESE+T offer the same functionality in an extended temperature range.
