MAX4523CEE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4523CEE 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 within a 16-pin QSOP package. The device operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. Key electrical parameters include an on-resistance of up to 100Ω, on-resistance flatness of 12Ω max, and off-leakage current of 1nA at +25°C. It supports rail-to-rail analog signals and provides 2kV ESD protection per Method 3015.7.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature range. Ensure compatibility with system voltage requirements and logic levels 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 switching functions is required in a compact form factor. Consider the on-resistance characteristics and leakage currents relative to the application's signal integrity needs. Verify that the operating temperature range meets the environmental conditions of the intended deployment.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage SPST analog switches. While sharing similar core specifications, each variant differs in switch configuration: MAX4521 offers four normally closed switches, MAX4522 provides four normally open switches, and MAX4523 combines two of each. This differentiation allows designers to choose the optimal topology without external logic inversion.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same family include MAX4521CEE and MAX4522CEE, provided the specific switch state (NO vs NC) aligns with the circuit design requirements. Other packages such as TSSOP (MAX4523CUE) or SOIC (MAX4523CSE) offer pin-compatible alternatives if footprint changes are permissible.
