MAX13080EESD+T

Drivers, Receivers, Transceivers Overview

The MAX13080EESD+T is a +5.0V, full-duplex RS-485 transceiver featuring one driver and one receiver in a 14-pin SO package. It supports data rates up to 250kbps with enhanced slew-rate limiting to minimize EMI. The device provides ±15kV human body model ESD protection on I/O pins and incorporates true fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. Hot-swap input structures on the DE and RE pins prevent false transitions during bus insertion. Supply current is typically 1.8mA at +5.0V, with a shutdown mode drawing 10µA maximum.

Drivers, Receivers, Transceivers Feature Summary

• Enhanced slew-rate limiting minimizes electromagnetic interference and reduces reflections from improperly terminated cables.
• True fail-safe receiver ensures a logic-high output state when differential inputs are open, shorted, or disconnected.
• Hot-swap input structures on enable pins eliminate erroneous data transfer during board insertion into powered backplanes.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official documentation to confirm tape-and-reel packaging and temperature range. Confirm lead-free status and RoHS compliance through manufacturer declarations. Validate pinout compatibility for the 14-SOIC footprint before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust ESD protection and hot-swap capability on RS-485 networks. Ensure the 250kbps data rate meets system requirements, as higher speeds require different family members. Verify that the full-duplex architecture aligns with the communication topology.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX13080E–MAX13089E family of +5.0V RS-485 transceivers manufactured by Analog Devices/Maxim Integrated. The family offers various speed options and duplex configurations within standardized packages.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13080EESD is the non-rohs equivalent. Other family members like MAX13083E or MAX13086E offer higher data rates but may lack identical thermal or electrical characteristics.

Drivers, Receivers, Transceivers FAQ

How does the fail-safe feature function?

The receiver guarantees a logic-high output if the differential input voltage (A-B) is greater than -50mV, covering conditions where inputs are open, shorted, or connected to a terminated line with all drivers disabled.

What is the purpose of the hot-swap capability?

Internal pull-down circuits on the DE and RE pins hold the transceiver in a disabled state during power-up or board insertion, preventing false transitions caused by leakage currents or parasitic capacitance.

What is the typical supply current?

The device draws a typical supply current of 1.8mA when unloaded or fully loaded with drivers disabled at +5.0V.
