MAX350CWN+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX350CWN+ is a dual 4-channel serially controlled multiplexer housed in an 18-pin Wide SOIC package. It operates on single supplies from +2.7V to +16V or dual supplies from ±2.7V to ±8V. The device features a maximum on-resistance of 100Ω with a channel-to-channel match of 16Ω and flatness of 10Ω. Turn-on time is typically 275ns, while turn-off time is 150ns at +5V single supply. Off-leakage current is 0.1nA at +25°C. The component supports SPI/QSPI/MICROWIRE interfaces and functions within a commercial temperature range of 0°C to +70°C.

• Industrial and process control systems
• Audio signal routing networks

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'C' confirms the commercial temperature range of 0°C to +70°C against the datasheet. Confirm the 'W' designation matches the 18-Wide SOIC physical footprint. Ensure the '+' indicates compliance with current environmental directives. Cross-reference the manufacturer's part numbering system to validate that no functional changes are implied by the ordering code.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 4-channel configuration is required rather than an 8-channel layout. Verify that the 100Ω maximum on-resistance meets the signal integrity requirements of the application. Ensure the operating voltage falls within the specified single or dual supply limits. Check that the serial interface timing parameters align with the host controller's clock capabilities.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX349/MAX350 family of low-voltage multiplexers. While the MAX349 provides a single 8-channel configuration, the MAX350 offers two independent 4-channel switches. Both share identical electrical characteristics and serial control logic, differing only in the number of available analog channels and pin assignments for the secondary switch bank.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX349 serves as a functional alternative if a single 8-channel multiplexer is acceptable instead of two separate 4-channel units. Other devices in the series may offer extended temperature ranges or different packaging options.
