MAX4569EUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4569EUK+T is a single-pole/single-throw (SPST) normally closed analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +1.8V to +12V supply and features ±15kV ESD protection on NO/NC terminals. The device offers a maximum on-resistance of 70Ω at +5V and 120Ω at +3V, with channel matching up to 3Ω and flatness up to 5Ω over the signal range. Off-leakage current is typically 0.5nA at +25°C. Switching times include a turn-on time of 150ns and turn-off time of 80ns at +5V. It utilizes a 5-pin SOT23 package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the component designation matches the specific SPST NC configuration required for the circuit design. Confirm that the 5-pin SOT23 footprint aligns with the PCB layout specifications. Ensure the supply voltage range accommodates the system's operational requirements. Check for RoHS compliance status if environmental regulations apply to the manufacturing process.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a normally closed analog path is necessary within a low-voltage environment. Consider the 70Ω on-resistance limit for signal integrity constraints. Evaluate the ±15kV ESD rating against the expected exposure levels in the target application. Verify that the 5-pin package size fits within the available board space constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX456x family of low-voltage CMOS analog switches. It shares pinout compatibility with the MAX4514 and MAX4515 devices. The series includes SPDT variants like the MAX4561 and normally open versions such as the MAX4568. All members utilize standard SOT23 packaging options.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4568EUK+T serves as a functional substitute if a normally open configuration is acceptable instead of normally closed. The MAX4514 and MAX4515 are pin-compatible alternatives within the same package type. Verify logic polarity differences when swapping between these specific variants.
