MAX4581AUE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4581AUE+T is a low-voltage, CMOS analog multiplexer IC configured as an 8-channel switch. It operates continuously with ±2V to ±6V dual power supplies or a +2V to +12V single supply. The device features guaranteed on-resistance of 80Ω at ±5V supplies and 150Ω at a single +5V supply. Off-leakage current is specified at 1nA at +25°C and 5nA at +85°C. Digital inputs have 0.8V to 2.4V logic thresholds for TTL/CMOS compatibility. The component is housed in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +125°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm the 'A' designation corresponds to the extended automotive temperature range (-40°C to +125°C). Ensure the '+T' suffix aligns with lead-free/RoHS compliance requirements for your manufacturing process. Cross-reference the 16-pin TSSOP footprint with your PCB design guidelines before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexing function is required within a compact surface-mount package. The wide single-supply operation up to 12V provides flexibility for various system architectures. Consider the guaranteed on-resistance match between channels if signal integrity across multiple paths is critical. Verify that the logic threshold levels are compatible with the controlling microcontroller or FPGA outputs.

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 one 8:1 multiplexer configuration. It is pin-compatible with industry-standard 74HC4051 devices but offers superior electrical characteristics such as lower leakage and guaranteed on-resistance matching. The A-grade variant extends the operational temperature range for demanding environments.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct functional substitutes include the MAX4051 series, which shares identical pinouts and logic diagrams. Other variants within the same family, such as the MAX4582 (dual 4-channel) or MAX4583 (triple SPDT), offer different channel configurations but maintain similar electrical profiles and package options.
