MAX4542EKA-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4542EKA-T is a dual single-pole/single-throw (SPST) analog switch from the MAX4541–MAX4544 series, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single supply voltage ranging from +2.7V to +12V and features two normally closed (NC) switches. The device provides a maximum on-resistance of 60Ω with a typical value of 33Ω at +5V. Key electrical parameters include a maximum turn-on time of 100ns, a maximum turn-off time of 75ns, and a maximum charge injection of 5pC. It supports a continuous current of ±10mA per terminal and offers low leakage currents of 100pA maximum. The component is housed in an SOT-23-8 package and is rated for an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging when sourcing this component. Confirm that the 'E' designation corresponds to the extended industrial temperature range of -40°C to +85°C. Ensure compatibility with the SOT-23-8 footprint during PCB layout. Cross-reference the manufacturer's latest documentation for any potential obsolescence notices or pinout revisions before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4542EKA-T when a dual normally closed analog switch is required for low-voltage single-supply applications. This part is appropriate for designs needing bidirectional signal routing with minimal on-resistance variation. Consider the 60Ω maximum on-resistance and 5pC charge injection limits against signal integrity requirements. Verify that the SOT-23-8 package dimensions fit within the available board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4541–MAX4544 family of precision dual analog switches. While the MAX4541 features normally open switches and the MAX4543 combines one normally open and one normally closed switch, the MAX4542 specifically provides two normally closed channels. All members of this series share similar electrical characteristics regarding speed, power consumption, and supply voltage ranges, differing primarily in their internal switch contact configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes within the same package include the MAX4541EKA-T and MAX4543EKA-T, provided the different switch states (normally open vs. normally closed) are acceptable for the circuit design.
