MAX4051CEE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4051CEE+ is a low-voltage CMOS analog multiplexer configured as an 8-channel switch in a 16-pin QSOP package. It operates on dual supplies from ±2.7V to ±8V or single supplies between +2.7V and +16V. The device features guaranteed on-resistance of 100Ω at ±5V, channel-to-channel match of 6Ω, and off-leakage current of 0.1nA at +25°C. Digital inputs are TTL/CMOS compatible with thresholds of 0.8V to 2.4V. Operating temperature range is 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CEE+' against official documentation to confirm the 16-pin QSOP package and commercial temperature range (0°C to +70°C). Ensure compatibility with existing board layouts by checking pin assignments against standard 74HC4051 equivalents. Confirm that supply voltage requirements align with the specified operational limits for your application design.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a direct replacement for 74HC4051 is required but lower leakage and better resistance matching are needed. The 'A' suffix ensures guaranteed on-resistance flatness and match specifications. Verify that the operating environment stays within the 0°C to +70°C range. Consider the 16-pin QSOP footprint during PCB layout planning.

Analog Switches, Multiplexers, Demultiplexers FAQ

What is the logic threshold voltage for the MAX4051?

The digital inputs have 0.8V to 2.4V logic thresholds, ensuring TTL/CMOS compatibility when using ±5V or a single +5V supply.

How does the MAX4051 handle overvoltage conditions?

Reverse ESD-protection diodes are internally connected between each analog signal pin and both V+ and V-. Signals exceeding these rails will cause the diodes to conduct.

Is the MAX4051 pin-compatible with other common multiplexers?

Yes, it is pin-compatible with industry-standard 74HC4051 devices.
