MAX4723EUA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4723EUA+T is a dual single-pole/single-throw (SPST) analog switch featuring one normally open and one normally closed channel. It operates from a single +1.8V to +5.5V supply with rail-to-rail signal handling. The device provides a maximum on-resistance of 4.5Ω at +3V and 3.0Ω at +5V, with an on-resistance match of 0.3Ω and flatness of 1.2Ω. Key electrical parameters include a 300MHz -3dB bandwidth, 15pF on-channel capacitance, and 9pF off-capacitance. Leakage current is less than 0.5nA at +25°C. The component supports break-before-make switching with a 1ns delay and features low charge injection of 5pC.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix '+T' indicates tape-and-reel packaging when sourcing components. Confirm that the 'E' designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with the 8-pin µMAX package dimensions during PCB layout review.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for designs requiring mixed normally open and normally closed channels within a dual-switch architecture. It is suitable for low-voltage systems operating between 1.8V and 5.5V where CMOS logic compatibility is required. Consider the 8-pin µMAX package constraints if space is limited.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4721/MAX4722/MAX4723 family of low-voltage analog switches. While the MAX4721 offers two normally open channels and the MAX4722 provides two normally closed channels, the MAX4723 uniquely combines one of each type. All variants share identical electrical characteristics and pinouts.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitutes include MAX4721EUA+T and MAX4722EUA+T. These parts share the same package and electrical specifications but differ in channel configuration: MAX4721 provides two normally open switches, while MAX4722 provides two normally closed switches.
