MAX13087EESA+T

Drivers, Receivers, Transceivers Overview

The MAX13087EESA+T is a full-duplex RS-485 transceiver operating from a single +5.0V supply (4.5V to 5.5V). It features one driver and one receiver with an 8-pin SO package. The device supports data rates up to 16Mbps with unrestricted slew rates. It includes ±15kV Human Body Model ESD protection on I/O pins, true fail-safe circuitry ensuring a logic-high output when inputs are open or shorted, and hot-swap capability for DE and RE inputs. Supply current is typically 1.8mA, with a shutdown mode drawing 2.8µA to 10µA. Operating temperature ranges from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Full-duplex communication architecture supporting high-speed data transmission up to 16Mbps without slew-rate limitations.
• Integrated hot-swap input structures on Driver Enable (DE) and Receiver Enable (RE) pins to prevent false transitions during bus insertion.
• True fail-safe receiver design that guarantees a logic-high output state when differential inputs are left open or shorted.
• Extended electrostatic discharge protection rated at ±15kV via the Human Body Model on all RS-485 I/O pins.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'ESAT' against official documentation to confirm tape-and-reel packaging and lead-free compliance status. Ensure the component matches the Analog Devices/Maxim Integrated manufacturing origin. Confirm the extended industrial temperature range (-40°C to +85°C) aligns with system requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring full-duplex RS-485 connectivity at speeds up to 16Mbps. It is suitable for environments demanding robust ESD protection and fail-safe behavior on unpowered buses. Verify compatibility with systems utilizing standard +5.0V logic levels and ensure the 8-pin SO footprint fits the target PCB layout constraints.

Drivers, Receivers, Transceivers Part Context

This device belongs to the MAX13080E–MAX13089E family of +5.0V RS-485 transceivers. While sharing core features like ESD protection and fail-safe operation, it differs from half-duplex variants by providing simultaneous transmit and receive paths. It complements slew-rate limited models by offering maximum throughput capabilities for high-bandwidth serial communication networks.

Drivers, Receivers, Transceivers Replacement Considerations

Direct functional replacements within the same family include the MAX13086E and MAX13088E, which share identical electrical characteristics and pinouts. When substituting, verify that the alternative part number maintains the full-duplex configuration and the specific thermal grade required for the application environment.

Drivers, Receivers, Transceivers FAQ

How does the MAX13087E handle bus contention during power-up?

It utilizes hot-swap input structures on the DE and RE pins. Internal circuitry holds the driver disabled and receiver enabled until the supply voltage stabilizes, preventing erroneous data transmission during board insertion or power sequencing.

What is the fail-safe threshold for the receiver?

The receiver guarantees a logic-high output if the differential input voltage (A minus B) is greater than or equal to -50mV. If the voltage drops below -200mV, the output goes low. This ensures a defined state even when the bus is idle or disconnected.

Does this device support low-power shutdown modes?

No, the datasheet explicitly excludes the MAX13087E from the list of devices featuring low-current shutdown modes. Only specific variants in the family, such as the MAX13080E and MAX13082E, offer this feature.
