MAX4504EUK+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4504EUK+ is a low-voltage, dual-supply, single-pole/single-throw (SPST), normally closed (NC) CMOS analog switch. 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. Digital inputs are CMOS-logic compatible using ±5V supplies. Electrical characteristics at ±5V include a guaranteed on-resistance of 250Ω, turn-on time of 150ns, and turn-off time of 100ns. Charge injection is limited to 10pC maximum. The component is housed in a 5-pin SOT23-5 package and supports an operating temperature range from -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EUK+' corresponds to the extended temperature range (-40°C to +85°C) and the SOT23-5 package type as documented in the official Maxim Integrated datasheet. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure supply voltages remain within the specified ±1V to ±6V limits during operation to maintain device reliability and performance specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4504EUK+ when a normally closed state is required upon power-up or logic low input, distinguishing it from the MAX4503 which is normally open. This part is suitable for applications requiring dual-supply operation and CMOS logic compatibility without a dedicated ground pin. Consider the ±5V supply performance metrics for on-resistance and leakage if operating at higher voltage rails compared to ±3V configurations.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4504EUK+ belongs to the MAX4503/MAX4504 family of low-voltage, dual-supply CMOS analog switches manufactured by Analog Devices / Maxim Integrated. It serves as the normally closed counterpart to the MAX4503. The 'E' designation indicates the industrial temperature grade, while 'UK' specifies the 5-pin SOT23 surface-mount package. These switches are designed for portable and battery-powered applications due to their low voltage requirements and low power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4501 and MAX4502 are pin-for-pin equivalents designed for single-supply operation instead of dual supplies. For normally open functionality, the MAX4503 series is the direct functional alternative. Verify that any substitute maintains the same SOT23-5 footprint and extends to the required -40°C to +85°C temperature range.
