MAX349EWN+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX349EWN+ is an 8-channel serially controlled multiplexer in an 18-pin Wide SO package. It supports dual supplies from ±2.7V to ±8V or a single supply from +2.7V to +16V. The on-resistance is 100Ω max, matched to 16Ω max and flat to 10Ω max over the signal range. Operating temperature ranges from -40°C to +85°C. Supply current is typically 72µA at V+ and 0.1µA at V-. Turn-on time is 275ns max and turn-off time is 300ns max at +5V single supply.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended industrial temperature range of -40°C to +85°C. Confirm the 'W' suffix corresponds to the 18-pin Wide SOIC package. Ensure the '+' suffix denotes compliance with current environmental directives. Cross-reference the manufacturer's official ordering guide to validate these designators against the base part number.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when eight individually controllable analog switches are required within a compact surface-mount footprint. The serial interface reduces digital pin count compared to parallel alternatives. Verify that the 100Ω on-resistance meets the application's signal integrity requirements. Ensure the operating voltage range aligns with the system's available power rails.

Analog Switches, Multiplexers, Demultiplexers Part Context

This device belongs to the MAX349/MAX350 family of low-voltage multiplexers. The MAX349 variant provides a single 8-to-1 configuration, whereas the MAX350 offers two independent 4-to-1 channels. Both share identical control logic and electrical characteristics, differing only in channel count and pinout arrangement.
