MAX4521CUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4521CUE+T is a quad, low-voltage, single-pole/single-throw (SPST) analog switch manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates with dual power supplies ranging from ±2V to ±6V or a single supply between +2V and +12V. The device features an on-resistance of 100Ω maximum, matched between switches to 4Ω maximum, with flatness of 12Ω maximum over the signal range. Each switch handles rail-to-rail analog signals. Off-leakage current is specified at 1nA at +25°C and 10nA at +85°C. Digital inputs have +0.8V and +2.4V logic thresholds for TTL/CMOS compatibility. The component is housed in a 16-pin TSSOP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, temperature range, and lead-free status. Ensure the component matches the required electrical specifications for the target application environment. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a quad SPST analog switch with low voltage operation is required. Consider the MAX4522 or MAX4523 variants if different switch states (normally open or mixed) are needed instead of the normally closed configuration provided by the MAX4521. Verify that the supply voltage range and on-resistance requirements align with the system design constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX4521CUE+T belongs to the MAX4521/MAX4522/MAX4523 family of quad, low-voltage, SPST analog switches. These devices are designed for applications requiring efficient signal routing in low-power environments. The C suffix indicates a commercial temperature range, while the UE suffix denotes the TSSOP package style. This family is widely used in portable and industrial electronics where space and power efficiency are critical.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Public confirmed substitute part numbers include MAX4521EUE+T for extended temperature range and MAX4521CGE+T for QFN packaging. Verify pinout compatibility and electrical characteristics before substitution.
