MAX4051CSE-T

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 supports single-supply operation from +2.7V to +16V and dual supplies from ±2.7V to ±8V. The device features rail-to-rail analog signal handling, TTL/CMOS logic compatibility, and guaranteed on-resistance of 100Ω at ±5V supplies. Key electrical parameters include a maximum channel-to-channel on-resistance match of 12Ω, off-leakage current of 1nA at +25°C, and turn-on time up to 275ns under single +3V supply conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the 0°C to +70°C temperature range and 16-Narrow SOIC package configuration. Confirm that the '-T' designation indicates tape-and-reel packaging if reel quantity is required. Cross-reference the manufacturer's latest ordering guide to ensure the part number matches current production status and RoHS compliance requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when pin compatibility with standard 74HC4051 is required alongside lower voltage operation. Ensure the application operates within the specified single or dual supply ranges. Verify that the 12Ω channel matching and 1nA leakage specifications meet the system's accuracy requirements. Consider thermal derating if operating near the upper temperature limit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX4051/A family of low-voltage CMOS analog switches manufactured by Analog Devices Inc./Maxim Integrated. The 'C' suffix denotes commercial temperature range (0°C to +70°C), while 'SE' specifies the 16-pin Narrow SOIC package. The 'T' suffix typically indicates tape-and-reel packaging for automated assembly processes.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The datasheet explicitly states the device is pin-compatible with industry-standard 74HC4051 parts. Designers should verify that the replacement meets the specific on-resistance and leakage requirements of the original design, as generic HC4051 variants may not offer the same guaranteed performance metrics.
