MAX13181EELB+T

Drivers, Receivers, Transceivers Overview

The MAX13181EELB+T is a +5.0V, ±15kV ESD-protected RS-485 transceiver in a 10-pin, 2mm x 2mm µDFN package. It supports selectable half-/full-duplex operation with a maximum data rate of 250kbps and features slew-rate limiting to minimize EMI. The device includes integrated pullup/pulldown resistors on control inputs and offers extended ESD protection (±15kV HBM). Operating over the -40°C to +85°C temperature range, it draws a typical supply current of 23mA and features a low-current shutdown mode drawing 2.5µA.

Drivers, Receivers, Transceivers Feature Summary

• Slew-rate limited driver output minimizes electromagnetic interference and reflections for error-free transmission up to 250kbps
• Integrated internal pullup and pulldown resistors on DE, RE, and H/F inputs reduce external component count
• Extended electrostatic discharge protection rated at ±15kV Human Body Model and ±12kV IEC 61000-4-2 Air-Gap Discharge
• Low-current shutdown mode reduces power consumption to 2.5µA typical for battery-powered applications

Drivers, Receivers, Transceivers Procurement Notes

Verify the ordering suffix '+T' indicates tape-and-reel packaging configuration. Confirm the 'E' suffix denotes the industrial temperature range of -40°C to +85°C. Ensure the 'L1022-1' package code matches the required 10-pin µDFN footprint for PCB layout compatibility.

Drivers, Receivers, Transceivers Selection Notes

Select this variant when space-constrained designs require a tiny 2mm x 2mm footprint. Choose the MAX13181E specifically for applications needing selectable half/full-duplex modes and reduced EMI via slew-rate limiting. Verify that the 250kbps maximum data rate meets system timing requirements compared to higher-speed alternatives.

Drivers, Receivers, Transceivers Part Context

This component belongs to the MAX13181E–MAX13184E family of high-speed RS-485 transceivers. It shares pinout and functional similarities with the MAX13182E, MAX13183E, and MAX13184E, differing primarily in duplex configuration options and maximum data rates. The family utilizes BiCMOS process technology for robust performance.

Drivers, Receivers, Transceivers Replacement Considerations

Pin-compatible alternatives within the same family include the MAX13182EELB+T (full-duplex only) and MAX13183EELB+T (full-speed driver). Verify that the replacement part's data rate and duplex mode align with the specific application requirements before substitution.

Drivers, Receivers, Transceivers FAQ

How does the MAX13181E achieve selectable duplex operation?

Duplex operation is selected by driving the H/F input high for half-duplex mode or leaving it unconnected/low for full-duplex mode.

What is the purpose of the slew-rate limiting feature?

Slew-rate limiting minimizes electromagnetic interference (EMI) and reduces signal reflections caused by improperly terminated cables, ensuring error-free transmission up to 250kbps.

How many transceivers can be supported on a single bus?

The device features a 1/8-unit-load receiver input impedance, allowing up to 256 transceivers to be connected in parallel on one communication line.
