MAX4523CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4523CSE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features two normally closed and two normally open switches in a 16-pin Narrow SO package. The device operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include a maximum on-resistance of 100Ω, an on-resistance match of 4Ω max, and off-leakage current of 1nA at +25°C. Turn-on time is typically 80ns and turn-off time is 40ns under dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm temperature range and package type. Ensure compatibility with system voltage requirements before integration. Cross-reference part numbers with authorized distributors to confirm authenticity and availability status.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mix of normally open and normally closed SPST switches is required within a single package. Consider the 100Ω on-resistance limit and 1nA leakage specifications for signal integrity requirements. Verify that the operating temperature range meets the environmental constraints of the target application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage SPST analog switches. The MAX4523 specifically combines two normally closed and two normally open switches, distinguishing it from the MAX4521 (all NC) and MAX4522 (all NO). All variants share identical pinouts and electrical characteristics except for switch configuration.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include MAX4521CSE and MAX4522CSE, provided the specific switch configuration (NC vs NO) aligns with circuit design requirements.
