MAX4051AESE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4051AESE is a low-voltage, CMOS analog multiplexer featuring eight channels in a single configuration. It operates with dual supplies from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device handles rail-to-rail analog signals with an on-resistance of 100Ω at ±5V supplies. Off-leakage current is specified at 0.1nA at +25°C. Digital inputs have logic thresholds of 0.8V to 2.4V for TTL/CMOS compatibility. It is housed in a 16-pin Narrow SO package and functions within a temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range of -40°C to +85°C. Confirm the 'S' designation corresponds to the narrow SOIC-16 package type. Ensure the 'A' suffix is present to guarantee characterized on-resistance match and flatness specifications. Cross-reference the manufacturer's ordering guide for any recent packaging or documentation updates.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with standard 74HC4051 is required alongside superior leakage characteristics. The A-suffix ensures guaranteed on-resistance matching across all channels. Verify that the operating voltage range aligns with the system's single or dual supply rails. Consider the package size constraints as it utilizes a 16-pin narrow SOIC footprint.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4051/A family of low-voltage CMOS analog switches. It serves as the 8-channel multiplexer variant within the series, distinct from the 4-channel (MAX4052) and SPDT switch (MAX4053) configurations. The A-suffix denotes enhanced electrical characterization compared to the base model.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible replacements include the standard MAX4051 without the A-suffix, though leakage and resistance guarantees will differ. Other families like SN74LV4051A offer similar functionality but may require voltage level verification.
