MAX4559CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4559CSE is a dual 4-to-1 analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates on single supplies from +2V to +12V or dual supplies of ±2V to ±6V. The device features two independent SP4T switches with TTL/CMOS-compatible digital inputs. Key electrical parameters include an on-resistance of 160Ω (±5V supply) or 220Ω (+5V supply), and a maximum off-leakage current of 1nA at +25°C. It provides ±15kV ESD protection on signal pins, operates within a 0°C to +70°C temperature range, and is housed in a 16-pin Narrow SO package.

• Communications circuits operating in high-ESD environments

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' to confirm the commercial temperature range (0°C to +70°C) and the 16-pin Narrow SOIC package format. Ensure that the ordering documentation explicitly references the Analog Devices / Maxim Integrated manufacturer designation to distinguish it from other potential suppliers or generic equivalents.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-to-1 multiplexing function is required within a low-voltage environment. It serves as a pin-compatible alternative to industry-standard 74HC4051/74HC4052 devices while offering superior ESD protection and lower distortion characteristics suitable for precision analog signal paths.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4558/MAX4559/MAX4560 family of low-voltage CMOS analog switches. While the MAX4558 offers an 8-to-1 configuration and the MAX4560 provides triple SPDT switching, the MAX4559 specifically addresses designs needing two separate 4-to-1 multiplexers within a compact footprint.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet confirms pin compatibility with industry-standard 74HC4051, 74HC4052, and 74HC4053 logic families. Designers replacing these standard logic parts should verify that the higher ESD protection and specific voltage thresholds meet the system requirements.
