MAX349CWN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX349CWN is an 8-channel serially controlled analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates within a temperature range of 0°C to +70°C and utilizes an 18-pin Wide SOIC package. The device supports dual power supplies ranging from ±2.7V to ±8V or a single supply between +2.7V and +16V. Key electrical specifications include a maximum on-resistance of 100Ω, an on-resistance match of 16Ω max, and an on-resistance flatness of 10Ω max over the signal range. The off-leakage current is specified at 0.1nA at +25°C and 5nA at +85°C. The component features >2kV ESD protection per Method 3015.7 and includes an asynchronous RESET input.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature grade (0°C to +70°C) against the manufacturer's official part numbering guide. Confirm the 'W' suffix corresponds to the 18-Wide SOIC package dimensions. Ensure compatibility with existing system voltage rails before procurement.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer with serial control is required. Verify that the application requires bidirectional signal flow and rail-to-rail operation. Ensure the system logic levels are compatible with the specified TTL/CMOS thresholds. Consider the package size constraints associated with the 18-Wide SOIC form factor.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX349/MAX350 family of low-voltage multiplexers. The MAX349 provides a single 8-to-1 configuration, whereas the MAX350 offers a dual 4-to-1 topology. Both share identical serial interface protocols and electrical characteristics, differing primarily in channel count and pinout arrangement.
