MAX4523ESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4523ESE is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates with dual supplies from ±2V to ±6V or a single supply between +2V and +12V. The device features four switches: two normally closed and two normally open. On-resistance is typically 100Ω max with ±5V supplies, matched to 4Ω max and flat to 12Ω max over the signal range. Off-leakage current is 1nA at +25°C and 10nA at +85°C. Logic inputs are TTL/CMOS compatible with thresholds of +0.8V and +2.4V. It is housed in a 16-pin Narrow SO package and operates within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

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

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a mixed NO/NC switch configuration is required within a quad SPST array. Verify that the on-resistance flatness and leakage current specifications meet the system requirements for the intended signal range and operating temperature. Confirm that the narrow SO package dimensions fit the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4523 is part of the MAX4521/MAX4522/MAX4523 family of quad, low-voltage SPST analog switches. While the MAX4521 provides four normally closed switches and the MAX4522 offers four normally open switches, the MAX4523 combines two of each type. This family shares similar electrical characteristics regarding on-resistance, leakage, and supply voltage ranges.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the difference between the MAX4521, MAX4522, and MAX4523?

The MAX4521 contains four normally closed (NC) switches. The MAX4522 contains four normally open (NO) switches. The MAX4523 contains two normally closed and two normally open switches.

Can the MAX4523 operate with a single supply?

Yes, the MAX4523 can operate with a single supply between +2V and +12V when the V- pin is connected to GND.

Are the NC and NO pins interchangeable on the MAX4523?

Yes, the NO_ and NC_ pins are identical and interchangeable. Either may be considered as an input or output, and signals pass equally well in either direction.
