MAX3483AEASA+

Drivers, Receivers, Transceivers Overview

The MAX3483AEASA+ is a half-duplex RS-485/RS-422 transceiver operating from a single 3.3V supply (3.0V to 3.6V). It supports data rates up to 250kbps with slew-rate-limited drivers. The device features ±20kV HBM ESD protection and includes fail-safe receiver inputs that guarantee a logic-high output when inputs are open or shorted. It incorporates hot-swap capability to prevent false transitions during power-up. The unit operates within an extended temperature range of -40°C to +125°C and is housed in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated ±20kV ESD protection on all pins for enhanced robustness
• Hot-swap functionality eliminates false transitions during board insertion
• Fail-safe receiver ensures logic-high output under open or shorted input conditions
• Low-power shutdown mode reduces current consumption below 10µA

Drivers, Receivers, Transceivers Applications

• Industrial-control local area networks
• Transceivers for EMI-sensitive applications
• Telecommunications systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the component against official Analog Devices documentation to confirm the specific suffix indicates the lead-free RoHS-compliant variant. Ensure the ordering information matches the exact package style and temperature grade required for the target design environment before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this model for half-duplex communication requiring high ESD immunity and operation in noisy industrial environments. The MAX3483AE is suitable for bus configurations supporting up to 32 units due to its 1-unit load impedance. Consider alternative family members if full-duplex operation or higher data rates are necessary.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX3483AE/MAX3485AE/MAX3488AE/MAX3490AE/MAX3491AE family of 3.3V-powered, ±20kV ESD-protected RS-485/RS-422 transceivers. These devices are optimized for extended cable runs in electrically noisy environments, providing reliable bidirectional data communications on multipoint bus transmission lines.
