MAX3488AEGSA+

Drivers, Receivers, Transceivers Overview

The MAX3488AEGSA+ is a full-duplex RS-422/RS-485 transceiver operating from a single 3.3V supply (3.0V to 3.6V). It features a 1/4-unit load receiver input impedance, supporting up to 128 nodes on the bus. The device provides ±20kV HBM ESD protection and short-circuit protected outputs. Electrical specifications include a maximum data rate of 20Mbps, typical driver propagation delay of 30ns, and receiver propagation delay of 35ns. Supply current is typically 1.9mA during operation and 10µA in shutdown mode. It operates within an industrial temperature range of -40°C to +105°C and is housed in an 8-pin SO package.

Drivers, Receivers, Transceivers Feature Summary

• Integrated hot-swap capability prevents false transitions during power-up or hot insertion
• True fail-safe receiver ensures logic-high output when inputs are open or shorted
• Enhanced electrostatic discharge protection meets IEC 61000-4-2 standards

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'E' corresponds to the extended temperature range (-40°C to +105°C) as defined in the official Analog Devices ordering information. Confirm the package type matches the required PCB footprint. Ensure the component source is authorized to guarantee authenticity and traceability for industrial deployments.

Drivers, Receivers, Transceivers Selection Notes

Select this model for full-duplex communication requirements where high node density is necessary. The 1/4-unit load impedance allows significantly more devices on the bus compared to standard unit-load alternatives. Verify that the system voltage aligns with the 3.3V supply requirement and that the thermal environment remains within the specified operational limits.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX3483AE family of +3.3V-powered, ±20kV ESD-protected RS-485/RS-422 transceivers. It shares core architectural features with half-duplex variants like the MAX3483AE but differs in duplex operation and bus loading capacity. The family is optimized for extended cable runs in noisy environments.
