MAX3443EEPA+

Overview

The MAX3443EEPA+ is a half-duplex RS-485 transceiver in an 8-pin PDIP package. It operates from a 5V supply (4.75V to 5.25V) with a maximum data rate of 10Mbps. The device features ±60V fault protection on the A and B pins, ±15kV ESD protection, and true fail-safe receiver inputs that guarantee a logic-high output when inputs are open or shorted. It includes hot-swap circuitry for telecom applications and low-power shutdown mode consuming a maximum of 20µA. Operating temperature range is -40°C to +85°C.

Feature Summary

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

Applications

• RS-422/RS-485 Communications
• Industrial Networks
• Telecommunications Systems

Procurement Notes

Verify the component against official Analog Devices documentation to confirm lead-free status and RoHS compliance. Ensure the specific ordering suffix matches the required package type and temperature rating. Cross-reference pin configurations and electrical characteristics directly with the manufacturer datasheet before integration.

Selection Notes

Select this model for systems requiring high-speed RS-485 communication up to 10Mbps with robust bus fault tolerance. The integrated ±60V protection eliminates the need for external protection components. Verify that the through-hole PDIP package aligns with the PCB layout requirements and thermal management strategy.

Part Context

This component belongs to the MAX3440E–MAX3444E family of fault-protected transceivers manufactured by Analog Devices / Maxim Integrated. The 'E' suffix indicates industrial temperature specifications, while 'P' denotes the PDIP package. The '+' suffix signifies lead-free and RoHS-compliant manufacturing.

Replacement Considerations

Compatible substitutes within the same family include MAX3440EESA+, MAX3441EEPA+, MAX3442EESA+, and MAX3444EEPA+. These parts share identical pinouts and core functionality but differ in data rates or slew-rate limiting features.
