MAX4503CUK

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4503CUK is a low-voltage, single-pole single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2 V to 12 V and features a maximum on-resistance of 250 Ohms. The device supports a maximum DC switch current of 10 mA and draws a maximum supply current of 1 uA. Key timing specifications include a maximum turn-on time of 75 ns, a maximum turn-off time of 50 ns, and a propagation delay of 350 ns. It is housed in an SOT-23-5 surface-mount package and functions reliably across an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and electrical tolerances. Ensure the component meets RoHS requirements if mandated by your project standards. Cross-reference the ordering part number with authorized distributors to confirm availability status and authenticity before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-channel analog switch is required with low voltage operation between 2 V and 12 V. Consider the 250 Ohm on-resistance limit for signal integrity requirements. Verify that the SOT-23-5 package fits the PCB layout constraints and that the 0°C to +70°C industrial temperature range aligns with the environmental conditions of the target application.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4501 series of low-voltage CMOS analog switches. The series provides similar functionality with variations in channel count and package options. The MAX4503CUK specifically offers a single SPST configuration in a compact SOT-23-5 footprint, distinguishing it from multi-channel variants or larger package types within the same family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for direct equivalents such as the MAX4501 series variants or other single-channel SPST switches from Analog Devices. Ensure replacement parts match the 2 V to 12 V supply range and SOT-23-5 package dimensions. Verify that on-resistance and timing parameters meet or exceed the original specifications.
