MAX4051ESE+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4051ESE+T is a low-voltage, CMOS analog multiplexer configured as an 8-channel switch. It operates with dual power supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device features rail-to-rail analog signal handling, TTL/CMOS-logic compatibility, and guaranteed on-resistance of 100Ω at ±5V supplies. It offers low off-leakage current (0.1nA at +25°C), low distortion (< 0.04%), and high off-isolation (> -90dB). The component is housed in a 16-pin Narrow SO package and supports an operating temperature range of -40°C to +85°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) and 'SE' denotes the narrow SOIC package. Confirm the '+T' designation matches the required tape-and-reel packaging format for automated assembly processes. Cross-reference the manufacturer's latest ordering guide to ensure compliance with current RoHS directives and material declarations before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this part when an 8-channel analog multiplexer is required within a standard 16-pin footprint. Ensure the application voltage stays within the specified limits to maintain the guaranteed 100Ω on-resistance. Verify that the logic levels of the controlling microcontroller align with the device's TTL/CMOS thresholds across the intended operating temperature range.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4051/A family of low-voltage CMOS analog switches manufactured by Analog Devices Inc./Maxim Integrated. It serves as a direct replacement for legacy 74HC4051 designs while offering improved electrical characteristics such as lower leakage and better on-resistance matching. The device is designed for applications demanding high reliability in compact surface-mount configurations.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the MAX4051ACSE+T and MAX4051AESE+. Verify that any alternative maintains the same 16-pin Narrow SO package dimensions and thermal performance specifications to ensure mechanical fit without redesigning the PCB layout.
