MAX350EPN

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX350EPN is a dual 4-channel serially controlled multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates within an extended industrial temperature range of -40°C to +85°C and utilizes a 20-pin SSOP package. The device supports dual power supplies from ±2.7V to ±8V or a single supply between +2.7V and +16V. Key electrical parameters include a maximum on-resistance of 100Ω, an on-resistance match of 16Ω max, and off-leakage current of 0.1nA at +25°C. Turn-on time is typically 275ns with a turn-off time of 150ns at +25°C under dual supply conditions.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific ordering suffix 'EPN' against the manufacturer's official documentation to confirm the exact temperature grade and package variant. Ensure compatibility with existing system voltage levels and serial communication protocols before integration. Confirm availability status as discontinued parts may require alternative sourcing strategies.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component for applications requiring bidirectional analog switching with low leakage and precise on-resistance matching. Verify that the required number of channels fits the dual 4-channel configuration. Ensure the operating environment falls within the specified -40°C to +85°C range and that the available power supply rails align with the device's operational limits.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX349/MAX350 family of serially controlled multiplexers. While the MAX349 provides a single 8-channel configuration, the MAX350 offers two independent 4-channel multiplexers in a single package. Both share identical serial interface logic and electrical characteristics, differing primarily in channel count and pinout arrangement.
