MAX3441EEPA+

Overview

The MAX3441EEPA+ is a half-duplex RS-485 transceiver in an 8-pin PDIP package, rated for -40°C to +85°C. It operates from a 5V supply (4.75V to 5.25V) with a typical normal operation current of 10mA and shutdown current of 10µA. The device supports data rates up to 10Mbps, featuring ±60V fault protection on A/B pins, ±15kV HBM ESD protection, and true fail-safe inputs. It includes hot-swap circuitry on DE/RE and allows up to 128 transceivers on the bus.

Feature Summary

• ±60V Fault Protection
• Hot-Swap Capability
• True Fail-Safe Receiver Inputs

Applications

• RS-485 Communications
• Industrial Networks
• Telecommunications Systems

Procurement Notes

Verify the specific ordering suffix EEPA+ corresponds to the 8-pin PDIP package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated by the plus sign. Ensure the component matches the Analog Devices/Maxim Integrated manufacturer designation before integration into production systems.

Selection Notes

Select this model when high-speed transmission up to 10Mbps is required alongside robust fault tolerance. The MAX3441E variant provides full-speed performance without slew-rate limiting, unlike the MAX3440E. The PDIP package is suitable for through-hole mounting applications requiring physical durability or prototyping flexibility.

Part Context

This component belongs to the MAX3440E–MAX3444E family of fault-protected RS-485/J1708 transceivers. It shares the same core architecture and pinout as other variants in the series, differing primarily in data rate capabilities and control logic configurations such as low-power shutdown modes.

Replacement Considerations

Direct functional replacements within the same family include MAX3441EESA+ (SOIC package) and MAX3443E variants (with shutdown mode). Verify package compatibility and thermal characteristics when substituting between SO and PDIP formats.

FAQ

Does the MAX3441EEPA+ support low-power shutdown?

No, the MAX3441E does not feature a low-power shutdown mode. Only the MAX3442E, MAX3443E, and MAX3444E variants include this functionality.

What is the maximum number of transceivers supported on the bus?

The 1/4-unit-load receiver input impedance allows up to 128 transceivers to be connected on a single communication bus.

How does the device handle bus faults?

The device features ±60V fault protection on the A and B pins, allowing it to withstand voltage faults resulting from shorts to the power grid without damage.
