MAX13080EESD+

Drivers, Receivers, Transceivers Overview

The MAX13080EESD+ 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 reduced slew-rate drivers to minimize EMI. The device operates within a supply voltage range of 4.5V to 5.5V and draws 1.8mA typical supply current. It provides ±15kV ESD protection on I/O pins and includes fail-safe circuitry that guarantees a logic-high receiver output when inputs are open or shorted. Hot-swap capability prevents false transitions during power-up or insertion.

Drivers, Receivers, Transceivers Feature Summary

• Hot-swap input structures on DE and RE pins prevent erroneous data transfer during board insertion into powered backplanes.
• True fail-safe receiver design ensures a logic-high output state when differential inputs are open, shorted, or disconnected from active drivers.
• Enhanced slew-rate limiting reduces signal reflections and electromagnetic interference for error-free transmission over improperly terminated cables.

• Utility meters
• Industrial control systems
• Security systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ESD+' indicates a lead-free, RoHS-compliant package configuration. Confirm the temperature grade corresponds to the extended commercial range (-40°C to +85°C) required for the application environment. Ensure the 14-pin SOIC footprint matches the target PCB layout constraints before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for full-duplex RS-485 networks requiring robust hot-swap protection and low electromagnetic interference. The fixed 250kbps maximum data rate suits applications where cable length or termination quality limits higher speeds. Verify that the system architecture does not require half-duplex operation or pin-selectable data rates, which are features of other family members like the MAX13089E.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13080E–MAX13089E family of high-speed RS-485 transceivers manufactured by Analog Devices/Maxim Integrated. While sharing core interface standards, this specific model is optimized for full-duplex communication at lower data rates compared to the 16Mbps variants in the same series.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13080ECPD+ serves as a direct replacement for the same functional specifications but operates within the commercial temperature range (0°C to +70°C). Substitutions must maintain the full-duplex topology and 14-pin SOIC package dimensions to ensure physical compatibility.

Drivers, Receivers, Transceivers FAQ

How does the fail-safe feature behave when all transmitters on the bus are disabled?

The receiver outputs a logic-high state if all transmitters on a terminated bus are disabled, ensuring the line remains in a known high state rather than floating.

What mechanism protects the device during hot insertion?

Internal pulldown circuits on the DE and RE pins hold the driver disabled and receiver enabled during power-up, preventing false transitions caused by leakage currents or parasitic capacitance.

Why are slew rates limited in this specific model?

Reduced slew rates minimize electromagnetic interference (EMI) and reduce signal reflections caused by improperly terminated cables, allowing for error-free data transmission.
