MAX4581EUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4581EUE+T is a low-voltage, CMOS analog multiplexer IC configured as an 8-channel switch (1 x 8:1). It operates with single supplies from +2V to +12V or dual supplies from ±2V to ±6V. The device features a maximum on-resistance of 80Ω at ±5V and 150Ω at +5V single supply. Off-leakage current is guaranteed at 1nA at +25°C. Logic inputs are TTL/CMOS compatible. It is housed in a 16-pin TSSOP package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type, temperature grade, and RoHS compliance status. Ensure the component source matches Analog Devices or Maxim Integrated specifications. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexing function is required within a compact surface-mount footprint. Consider the 80Ω on-resistance specification relative to the target load impedance to ensure acceptable signal attenuation. Verify that the system's logic voltage levels align with the device's TTL/CMOS input thresholds for reliable switching control.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4581/MAX4582/MAX4583 family of low-voltage CMOS analog switches. The MAX4581 specifically provides an 8:1 multiplexer configuration, distinguishing it from the dual 4-channel MAX4582 and the triple SPDT MAX4583 variants. All members share pin compatibility with industry-standard CD4051/4052/4053 devices.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Pin-compatible alternatives include the MAX4051 series and standard 74HC4051 logic families, though electrical parameters such as on-resistance and leakage may differ significantly.
