MAX13443EASA+

Drivers, Receivers, Transceivers Overview

The MAX13443EASA+ is a half-duplex RS-485 transceiver in an 8-pin SO package. It supports data rates up to 10Mbps with ±60V fault protection on the A and B pins. The device operates from a 5V supply (4.75V to 5.25V) and features true fail-safe receiver inputs that guarantee a logic-high output when inputs are open or shorted. It includes hot-swap circuitry for DE and RE pins, ±15kV ESD protection, and foldback current limiting. The receiver input impedance is 1/4-unit-load, allowing up to 128 transceivers on a single bus.

Drivers, Receivers, Transceivers Feature Summary

• Hot-swap capability prevents false transitions during board insertion into live backplanes
• True fail-safe receiver inputs ensure a logic-high state under open, shorted, or idle conditions
• Foldback current limit protects against excessive power dissipation during short circuits

Drivers, Receivers, Transceivers Applications

• RS-422/RS-485 communications
• Truck and trailer applications
• Industrial networks
• Telecommunications systems
• Automotive applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix matches the required packaging format. Confirm the component meets RoHS compliance standards for lead-free assembly. Ensure the automotive temperature range specification aligns with the target operating environment requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this model when high-speed transmission up to 10Mbps is required alongside robust fault protection. The MAX13443E differs from the MAX13442E and MAX13444E by lacking slew-rate limiting, which allows faster data rates but may increase EMI. Verify that the ±60V fault protection rating is sufficient for the specific bus voltage fault scenarios present in the design.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13442E/MAX13443E/MAX13444E family of fault-protected RS-485 and J1708 transceivers. All variants share the same 8-pin SO package and pinout configuration. The primary distinction within the family lies in the maximum data rate and the presence or absence of slew-rate limiting on the driver output stage.

Drivers, Receivers, Transceivers Replacement Considerations

MAX13442EASA+ offers identical pinout and fault protection but limits data rates to 250kbps due to slew-rate limiting. MAX13444EASA+ provides J1708 compatibility with similar speed constraints. Direct functional substitution requires verifying that the reduced data rate of these alternatives does not impact system timing requirements.
