MAX3488EEPA+

Overview

The MAX3488EEPA+ is a full-duplex RS-485/RS-422 transceiver operating from a single +3.3V supply without a charge pump. It features one driver and one receiver with slew-rate-limited outputs for error-free transmission up to 250kbps. The device provides ±15kV ESD protection on I/O pins, fail-safe receiver inputs, and thermal shutdown for driver overload protection. It operates within an extended temperature range of -40°C to +85°C and utilizes an industry-standard pinout.

Feature Summary

• Slew-rate-limited drivers minimize electromagnetic interference (EMI) and reduce signal reflections caused by improperly terminated cables.
• Enhanced electrostatic discharge (ESD) protection on all transmitter outputs and receiver inputs ensures robustness against high-voltage static events.
• Fail-safe receiver inputs guarantee a logic-high output state when both differential inputs are left open-circuited.
• Driver outputs incorporate short-circuit current limiting and thermal shutdown circuitry to prevent excessive power dissipation.

Applications

• Telecommunications systems
• Industrial-control local area networks
• Transceivers for EMI-sensitive applications
• Integrated Services Digital Networks (ISDN)
• Packet switching networks

Procurement Notes

Verify the specific suffix 'EEPA+' corresponds to the required plastic DIP package and extended industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status through official manufacturer documentation or authorized distributors before finalizing procurement specifications.

Selection Notes

Select this component for full-duplex communication requirements where low electromagnetic emissions are critical due to its slew-rate-limited driver characteristics. Ensure the application supports the 250kbps maximum data rate and operates within the specified 3.0V to 3.6V supply voltage range.

Part Context

This device belongs to the MAX3483E family of low-power transceivers designed for RS-485 and RS-422 communications. It shares core architectural features with siblings like the MAX3490E but differs in duplex mode and data rate capabilities. The EEPA+ designation specifically identifies the 8-pin Plastic DIP package variant suitable for through-hole mounting.

FAQ

Does the MAX3488EEPA+ support half-duplex operation?

No, the MAX3488E is designed exclusively for full-duplex communication. Half-duplex versions in this family include the MAX3483E, MAX3485E, and MAX3486E.

What is the maximum data rate supported by the MAX3488EEPA+?

The MAX3488EEPA+ supports data rates up to 250kbps. Higher speeds such as 12Mbps are available in other family members like the MAX3490E.

How does the device protect against driver overloads?

The driver outputs feature short-circuit current limiting and thermal shutdown circuitry. If excessive power dissipation occurs, the thermal shutdown forces the outputs into a high-impedance state.
