Analog Switches, Multiplexers, Demultiplexers datasheet and documents for MAX349CPN+

MAX349CPN+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX349CPN+ is an 8-channel serially controlled multiplexer housed in an 18-pin Plastic DIP package. It operates with dual supplies from ±2.7V to ±8V or a single supply between +2.7V and +16V. The device features a maximum on-resistance of 100Ω, matched to 16Ω max, with flatness of 10Ω max. Operating temperature range is 0°C to +70°C. Key electrical parameters include turn-on time up to 500ns (single +5V) and off-leakage current of 0.1nA at +25°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix CPN indicates the 18-pin Plastic DIP package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status as the datasheet lists non-RoHS variants within the same family. Ensure the source document matches the Analog Devices/Maxim Integrated part number exactly before ordering.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when an 8-channel multiplexer with serial control is required. Verify that the application voltage falls within the +2.7V to +16V single supply or ±2.7V to ±8V dual supply limits. Consider the 100Ω on-resistance and 500ns switching speed against system requirements. Check if the 18-pin DIP package fits the PCB layout constraints.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX349 belongs to the MAX349/MAX350 family of low-voltage multiplexers. While the MAX350 offers dual 4-channel configuration, the MAX349 provides a single 8-channel structure. Both share identical serial interface logic and electrical characteristics, differing primarily in channel count and pinout mapping for the additional channels.
