MAX4581ASE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4581ASE+ is a low-voltage, CMOS analog multiplexer configured as an 8-channel switch. It operates with dual supplies of ±2V to ±6V or a single supply of +2V to +12V. The device handles rail-to-rail analog signals and features TTL/CMOS-compatible digital inputs. Key electrical parameters include a maximum on-resistance of 150Ω at +5V single supply and 80Ω at ±5V dual supply. Off-leakage current is specified at 1nA at +25°C. The component supports an automotive temperature range from -40°C to +125°C and is housed in a 16-pin Narrow SO package.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and lead-free status. Ensure the selected variant matches the required operating temperature range for the intended environment. Cross-reference the part number with authorized distributors to confirm availability and authenticity before finalizing procurement plans.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when designing systems requiring high channel density within a compact footprint. The narrow SO package facilitates surface-mount assembly. Consider the guaranteed on-resistance match between channels if signal integrity across multiple paths is critical. Verify that the supply voltage constraints align with the system's power architecture.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4581/MAX4582/MAX4583 family of low-voltage CMOS analog switches. While the MAX4582 offers two 4-channel multiplexers and the MAX4583 provides three SPDT switches, the MAX4581 specifically integrates eight independent channels into a single 16-pin configuration. This structure allows for efficient signal routing in space-constrained designs.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4581EUE+ serves as a direct functional replacement offering identical specifications but rated for the industrial temperature range (-40°C to +85°C). Designers must verify that the reduced thermal tolerance of the E-series variant meets the operational requirements of the target application.
