MAX4051CSE

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4051CSE is a low-voltage CMOS analog multiplexer featuring eight independent channels. 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 TTL/CMOS logic compatibility. Key electrical parameters include a maximum on-resistance of 125Ω at ±5V, an off-leakage current of 1nA at +25°C, and a channel-to-channel match of 12Ω. Switching times are characterized by a turn-on time of up to 225ns and a turn-off time of 200ns under dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CSE' corresponds to the 16 Narrow SO package and the 0°C to +70°C operating temperature range. Confirm that the component meets RoHS3 compliance standards as indicated in manufacturer documentation. Ensure the ordering information matches the exact part number to avoid discrepancies in package type or thermal rating.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer is required for low-voltage applications. It serves as a drop-in replacement for standard 74HC4051 parts while offering improved leakage performance. Consider the guaranteed on-resistance match if channel uniformity is critical for the application design.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device 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 variant specifically provides an 8:1 multiplexing configuration within a 16-pin package architecture shared across the series.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX4051CSE is pin-compatible with the 74HC4051. Other family members such as the MAX4052ACSE (4-channel) and MAX4053ACSE (SPDT) share the same footprint but offer different switching configurations.
