MAX13443EASA+T

Drivers, Receivers, Transceivers Overview

The MAX13443EASA+T 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 bus lines. The device operates from a single +4.75V to +5.25V supply, drawing 10mA during normal operation and 20µA maximum in shutdown mode. It features true fail-safe receiver inputs that guarantee a logic-high output when inputs are open or shorted. Integrated hot-swap circuitry prevents false transitions during board insertion into live backplanes. The component includes ±15kV ESD protection and foldback current limiting for driver robustness.

Drivers, Receivers, Transceivers Feature Summary

• Hot-swap capability eliminates false data transitions during connection to powered backplanes
• True fail-safe receiver inputs ensure a logic-high state under open, shorted, or idle line conditions
• Integrated ±60V fault protection on differential bus lines removes need for external protection components
• Foldback current limiting and thermal shutdown protect against excessive power dissipation

Drivers, Receivers, Transceivers Applications

• RS-422/RS-485 communications networks
• Truck and trailer telematics systems
• Industrial network control systems
• Telecommunications infrastructure equipment
• Automotive electronic control units

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix '+T' corresponds to tape-and-reel packaging rather than tube configuration. Confirm the 'E' designation indicates automotive-grade qualification over the -40°C to +125°C temperature range. Ensure the datasheet revision matches the required specifications for your design implementation.

Drivers, Receivers, Transceivers Selection Notes

Select this model specifically for high-speed applications requiring 10Mbps transmission, as the sibling MAX13442E and MAX13444E are limited to 250kbps due to slew-rate limiting. Verify that the ±60V fault tolerance meets the system's bus voltage requirements, noting that other variants offer ±80V protection. Ensure the 5V supply voltage aligns with the controller logic levels.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX1344x family of fault-protected transceivers designed for harsh electrical environments. The series differentiates models based on data rate capabilities and specific protocol support, such as J1708 compliance found in the MAX13444E variant. All members share identical pinouts and physical dimensions to facilitate direct replacement within existing designs.

Drivers, Receivers, Transceivers Replacement Considerations

MAX13442EASA+T: Compatible but limited to 250kbps data rate with enhanced slew-rate limiting for reduced EMI. MAX13444EASA+T: Designed for J1708 protocols with 250kbps speed and ±80V fault protection.
