MAX4581CPE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4581CPE is a low-voltage CMOS analog multiplexer IC configured as an 8-channel, 1x8:1 switch. It operates with single supplies from +2V to +12V or dual supplies from ±2V to ±6V. The device handles rail-to-rail analog signals and features TTL/CMOS-compatible digital inputs. Key electrical parameters include a maximum on-resistance of 80Ω at ±5V supplies and 150Ω at +5V single supply. Off-leakage current is specified at 1nA at +25°C. The component is housed in a 16-pin Plastic DIP package and supports an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE' corresponds to the 16-pin Plastic DIP package and the commercial 0°C to +70°C temperature grade. Confirm that the ordering information matches the required supply voltage and leakage specifications for the target application environment before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when an 8-channel multiplexing function is required within a standard 16-pin DIP footprint. Ensure the design accommodates the specified on-resistance limits under the intended single or dual supply conditions. Verify that the logic thresholds align with the microcontroller or driver interface levels used in the circuit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component 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 delivers a single 8-channel configuration. All variants share similar electrical characteristics and pinout compatibility.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet notes pin compatibility with industry-standard 74HC4051 and Maxim's MAX4051 devices. These may serve as functional substitutes if the specific electrical tolerances of the MAX4581 are not strictly required.
