MAX13412EESA+T

Drivers, Receivers, Transceivers Overview

The MAX13412EESA+T is a half-duplex RS-485-compatible transceiver featuring an internal low-dropout regulator (LDO) and AutoDirection control. It operates from a supply voltage range of +6.0V to +28V, with the LDO generating a stable +5V output capable of sourcing up to 20mA for external circuitry. The device supports data rates up to 500kbps with slew-rate limiting to minimize EMI. It includes ±15kV Human Body Model ESD protection on bus pins and fail-safe receiver circuitry. Packaged in an 8-pin SOIC with an exposed paddle for thermal dissipation, it functions reliably across an extended temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• AutoDirection architecture eliminates separate driver enable and receiver enable signals by automatically controlling transmission direction based on the driver input state.
• Integrated low-dropout regulator accepts unregulated input voltages up to 28V and provides a regulated 5V output for powering auxiliary components.
• Enhanced electrostatic discharge protection rated at ±15kV on the A and B bus lines using the Human Body Model standard.

Drivers, Receivers, Transceivers Applications

• Isolated RS-485 communication interfaces
• Utility metering systems
• Industrial equipment networking

Drivers, Receivers, Transceivers Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the presence of the exposed paddle on the package bottom for proper thermal management during installation. Ensure the ordering suffix matches the tape-and-reel packaging format required for automated assembly processes.

Drivers, Receivers, Transceivers Selection Notes

Select this model when designing isolated RS-485 networks requiring simplified control logic without discrete isolation barriers. The integrated LDO allows direct connection to higher voltage buses, reducing external component count. Choose this variant over non-AutoDirection models to minimize system complexity and optical isolator requirements.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13410E–MAX13415E family of RS-485 transceivers optimized for isolated applications. While sharing the same internal LDO and thermal package, other family members differ in data rate capabilities and control architectures. This specific part combines the 500kbps slew-rate limited performance with the proprietary AutoDirection feature set.

Drivers, Receivers, Transceivers Replacement Considerations

Direct pin-compatible replacements within the series include the MAX13410EESA+ and MAX13414EESA+. Note that these alternatives lack the AutoDirection feature and require separate DE and RE control signals. Verify functional compatibility regarding control logic before substituting.
