MAX382EWN+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX382EWN+ is a low-voltage CMOS 1-of-8 multiplexer housed in an 18-pin Wide SO package. It operates from a single +2.7V to +16.5V supply or ±3V to ±8V dual supplies. Key electrical parameters include a maximum on-resistance of 100Ω, with channel matching within 4Ω and flatness up to 20Ω. Leakage current is less than 2.5nA at +85°C, and charge injection is guaranteed at 10pC maximum. The device supports TTL/CMOS logic inputs and features latchable digital inputs for address control.

Analog Switches, Multiplexers, Demultiplexers Feature Summary

• Pin-compatible with industry-standard DG428/DG429 and DG528/DG529 devices
• Features latchable digital inputs for simplified microprocessor interfacing
• Operates with both single-supply (+2.7V to +16.5V) and bipolar supplies (±3V to ±8V)
• Provides low power consumption and high off-isolation characteristics

Analog Switches, Multiplexers, Demultiplexers Applications

• Battery-operated systems
• Audio signal routing
• Low-voltage data-acquisition systems
• Sample-and-hold circuits
• Automatic test equipment

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) compared to the commercial 'C' variant. Confirm the 'W' suffix corresponds to the 18-Wide SOIC package. Ensure compatibility with existing PCB footprints designed for DG428/DG429 pinouts before finalizing procurement orders.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select the MAX382EWN+ when an 8-channel configuration is required rather than the dual 4-channel MAX384. The 'E' grade is necessary for industrial environments requiring operation down to -40°C. Verify that the 100Ω on-resistance meets the signal integrity requirements of the application, as lower resistance options may be needed for high-current paths.

Analog Switches, Multiplexers, Demultiplexers Part Context

This component belongs to the Maxim Integrated MAX382/MAX384 family of low-voltage analog multiplexers. It serves as a direct replacement for older CMOS switch technologies like the DG428. The E-series designation specifically denotes the industrial temperature rating, distinguishing it from the commercial C-series variants within the same functional family.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Direct pin-compatible substitutes include the DG428, DG429, DG528, and DG529. Designers should verify that the on-resistance and leakage specifications of these alternatives meet the system requirements before swapping components.
