MAX4051CSE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4051CSE+T 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 signal handling, TTL/CMOS logic compatibility, and guaranteed on-resistance of 100Ω at ±5V. Off-leakage current is specified at 1nA maximum at +25°C for the non-A suffix version. Operating temperature range is 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm package type and temperature rating. Ensure the component matches the required electrical specifications for your application before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit products.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with standard 74HC series is required alongside low-voltage operation. Consider the MAX4051A variant if stricter leakage and resistance matching specifications are necessary. Evaluate power supply constraints to determine suitability for single or dual supply configurations.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the MAX4051/A family of low-voltage CMOS analog switches manufactured by Analog Devices / Maxim Integrated. The family includes multiplexers (MAX4051/A), dual 4-channel multiplexers (MAX4052/A), and SPDT switches (MAX4053/A). The CSE suffix indicates a commercial temperature range and Narrow SO packaging.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states pin compatibility with the industry-standard 74HC4051. Verify that the replacement meets the specific voltage and leakage requirements of the original design.
