MAX4051ESE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4051ESE+ is a low-voltage, CMOS analog multiplexer configured as an 8-channel switch in a 16-pin Narrow SO package. It operates with dual supplies 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. Key electrical parameters include off-leakage current of 0.1nA at +25°C, channel-to-channel crosstalk below -90dB, and high off-isolation exceeding -90dB.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C. Confirm the '+' suffix denotes compliance with RoHS standards. Ensure the Narrow SO package matches the target PCB footprint. Cross-reference the manufacturer's latest datasheet for any updates to absolute maximum ratings or ordering information before finalizing procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel analog multiplexer is required within a standard 16-pin footprint. The MAX4051 is suitable for designs needing rail-to-rail signal transmission and low leakage. Consider the MAX4052 if two independent 4-channel switches are preferred, or the MAX4053 for three SPDT configurations. Verify that the operating voltage range aligns with the system's power supply constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4051/A, MAX4052/A, and MAX4053/A family of low-voltage CMOS analog switches manufactured by Analog Devices / Maxim Integrated. The MAX4051 specifically provides an 8:1 multiplexing configuration. The family shares common architectural features, including CMOS construction and low-power operation, designed for general-purpose signal switching in compact electronic systems.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4051 is pin-compatible with the 74HC4051. Other members of the same family, such as the MAX4052 (two 4:1 multiplexers) and MAX4053 (three SPDT switches), share the same 16-pin package and may be considered if the channel count or topology differs from the required 8:1 configuration.
