MAX13088ECSA+T

Drivers, Receivers, Transceivers Overview

The MAX13088ECSA+T is a half-duplex RS-485 transceiver in an 8-pin SO package. It operates on a single +5.0V supply (4.5V to 5.5V) with a typical quiescent current of 1.8mA and shutdown current of 2.8µA to 10µA. The device supports data rates up to 16Mbps with driver propagation delays ranging from 50ns to 1800ns. It features ±15kV ESD protection, true fail-safe receivers, and hot-swap inputs on DE and RE pins.

Drivers, Receivers, Transceivers Feature Summary

• Hot-swap input structures on DE and RE pins prevent false bus transitions during power-up or insertion.
• True fail-safe receiver guarantees a logic-high output when inputs are open or shorted.
• Extended electrostatic discharge protection rated at ±15kV for RS-485 I/O pins.

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 certificates. Ensure the ordering code matches the exact half-duplex variant required for the design.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring high-speed RS-485 communication up to 16Mbps. Verify that the system environment accommodates the specified operating temperature range. Ensure the bus topology supports the 1/8-unit load configuration allowing multiple devices.

Drivers, Receivers, Transceivers Part Context

This part belongs to the MAX13080E–MAX13089E family of +5.0V RS-485 transceivers. It shares core architectural features like fail-safe circuitry and hot-swap capability with siblings such as the MAX13080E and MAX13087E, differing primarily in duplex mode and slew-rate limitations.

Drivers, Receivers, Transceivers Replacement Considerations

The MAX13088E serves as the non-compliant predecessor. Other family members like the MAX13080E offer similar functionality but operate in full-duplex mode rather than half-duplex.

Drivers, Receivers, Transceivers FAQ

How does the MAX13088E handle bus contention during hot insertion?

It utilizes hot-swap input structures on the DE and RE pins that hold the driver disabled and receiver enabled during power-up, preventing erroneous data transmission.

What is the receiver behavior when the bus lines are disconnected?

The true fail-safe circuitry ensures the receiver output remains in a logic-high state if the A and B inputs are open or shorted.
