MAX4504CUK-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4504CUK-T is a low-voltage, dual-supply, single-pole/single-throw (SPST) CMOS analog switch manufactured by Analog Devices Inc./Maxim Integrated. It features a normally closed (NC) configuration and operates with dual supplies between ±1V and ±6V. The device handles rail-to-rail analog signals with an on-resistance of 250Ω at ±5V supplies. Key electrical parameters include off-leakage current of 1nA at +25°C and 10nA at +85°C, on-leakage current of 2nA at +25°C, and charge injection of 10pC maximum. Switching speeds are defined by a turn-on time of 150ns and a turn-off time of 100ns. It is housed in a SOT23-5 package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix for tape-and-reel packaging when sourcing the MAX4504CUK-T variant. Confirm that the component meets the required temperature range specifications for your application environment. Ensure compatibility with existing supply voltages before integration into the circuit design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX4504CUK-T for applications requiring a normally closed analog switch in a compact SOT23-5 package. This part is suitable for dual-supply systems operating between ±1V and ±6V. Consider the MAX4503 if a normally open configuration is needed instead. Verify logic level compatibility with the system's control voltage.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4504 is part of the MAX4503/MAX4504 family of low-voltage CMOS analog switches. It serves as the normally closed counterpart to the MAX4503, which is normally open. Both devices share identical pinouts and electrical characteristics except for their default switch states. They are designed for portable and battery-powered applications due to their low power consumption.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4501/MAX4502 are listed as pin-for-pin equivalents for single-supply operation. No other direct substitutes are documented in the provided datasheet.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the default state of the MAX4504 switch?

The MAX4504 is a normally closed (NC) switch, meaning the connection between COM and NC is established when the input is low.

Does the MAX4504 require a ground pin?

No, the MAX4504 has no ground pin. The digital input is CMOS-logic compatible even without a ground connection.

What is the maximum charge injection for this device?

The guaranteed maximum charge injection is 10pC.
