MAX4581CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4581CPE+ is a low-voltage, CMOS analog multiplexer IC 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 features rail-to-rail analog signal handling and TTL/CMOS logic compatibility at +5V. Key electrical parameters include a maximum on-resistance of 80Ω (±5V) or 150Ω (+5V), off-leakage current of 1nA at +25°C, and power-supply current of 1µA. It is housed in a 16-pin PDIP package with an operating temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix CPE+ corresponds to the commercial temperature range and 16-pin PDIP package configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure supply voltage sequencing adheres to absolute maximum ratings to prevent device damage during power-up and power-down cycles.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer is required within a 16-pin footprint. Verify that the 80Ω on-resistance specification meets the system's signal integrity requirements under the intended supply voltage conditions. Consider the 0°C to +70°C operating range against environmental constraints; utilize the E-series variants if extended industrial temperatures are necessary.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4581/MAX4582/MAX4583 family of low-voltage CMOS analog switches manufactured by Analog Devices Inc./Maxim Integrated. The MAX4581 variant specifically provides a single 8:1 multiplexer configuration. It is pin-compatible with industry-standard 74HC4051 devices but offers superior electrical performance characteristics such as lower leakage and guaranteed on-resistance matching.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4581EPE+ serves as a direct replacement offering an extended industrial temperature range (-40°C to +85°C) while maintaining identical pinout and electrical specifications. Other package variants such as MAX4581CSE+ or MAX4581CUE+ provide alternative form factors without changing functional behavior.
