MAX3440EAPA+

Overview

The MAX3440EAPA+ is a fault-protected RS-485 transceiver manufactured by Analog Devices/Maxim Integrated. It operates from a single +4.75V to +5.25V supply and supports data rates up to 250kbps with enhanced slew-rate limiting. The device features ±60V fault protection on the A and B bus lines, ±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 modes. The component is housed in an 8-pin PDIP package and is specified for operation over the automotive temperature range of -40°C to +125°C.

Feature Summary

RS-422/RS-485 Communications
Industrial Networks
Telecommunications Systems
HVAC Controls

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature rating. Confirm RoHS compliance status as indicated by the '+' designation. Ensure compatibility with system voltage requirements and interface standards before procurement.

Selection Notes

Select this part for applications requiring robust fault protection on RS-485 buses. The enhanced slew-rate limiting minimizes EMI and reflections, making it suitable for noisy industrial environments. Verify that the 250kbps maximum data rate meets system timing requirements compared to higher-speed variants.

Part Context

This component belongs to the MAX3440E–MAX3444E family of fault-protected transceivers. The 'APA+' suffix indicates an 8-pin PDIP package with an automotive temperature range (-40°C to +125°C) and lead-free/RoHS-compliant construction. Other variants in the series offer different packages or industrial temperature ranges.

Replacement Considerations

Direct substitutes within the same family include MAX3440EEPA+ (industrial temp, PDIP), MAX3440EESA+ (industrial temp, SOIC), and MAX3440EASA+ (automotive temp, SOIC). Ensure pinout and electrical characteristics match the original design requirements.
