MAX4503CUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4503CUK-T is a low-voltage, dual-supply, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It operates continuously with dual supplies between ±1V and ±6V and handles rail-to-rail analog signals. The device features an off-leakage current of 1nA at +25°C and 10nA at +85°C. It utilizes a unique logic input architecture for CMOS-logic compatibility without a ground pin. The component is housed in a SOT23-5 package and supports an operating temperature range from 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging configuration as per Maxim Integrated standards. Confirm that the 'C' suffix corresponds to the commercial temperature range of 0°C to +70°C. Ensure the source documentation explicitly lists this exact part number variant to avoid confusion with other package options or extended temperature grades within the MAX4503 family.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4503CUK-T when a normally open SPST switch is required for low-voltage dual-supply applications. This model is suitable for designs needing CMOS-compatible control without a dedicated ground pin. Consider the SOT23-5 package for space-constrained surface-mount layouts. Verify that the ±1V to ±6V supply range aligns with the system's power constraints and that the 0°C to +70°C temperature rating meets environmental requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4503CUK-T belongs to the MAX4503/MAX4504 series of low-voltage, dual-supply, SPST CMOS analog switches. The MAX4503 variant specifically provides a Normally Open (NO) configuration, whereas the MAX4504 offers a Normally Closed (NC) option. Both share identical electrical characteristics and pinouts, differing only in their default switch state. The CUk designation identifies the commercial temperature grade and SOT23-5 surface-mount package.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4501 and MAX4502 are noted as pin-for-pin equivalents designed for single-supply operation. These alternatives should be evaluated if the application requires a single positive voltage supply instead of a dual-supply configuration. Ensure the replacement part matches the required Normally Open or Normally Closed functionality.
