Product details

2.5 Mbps full-duplex RS-485/RS-422 link

The MAX491ECSD+T: The commercial temperature range (0°C to 70°C) suits indoor control and instrumentation backplanes rather than extended industrial or automotive environments.

Supply rail and signal margin

With a single driver/receiver pair, the MAX491ECSD+T is sized for point-to-point or multi-drop RS-485 networks where only one node transmits at a time — the full-duplex pair means the same twisted pair carries transmit and receive simultaneously.

14-SOIC footprint and tape-and-reel delivery

Housed in a 14-lead SOIC (3.90 mm body width), the part mounts on the standard 1.27 mm pitch SOIC footprint — the package is common enough that no special paste stencil or reflow profile is needed beyond the JEDEC MS-012 variation.

Frequently asked questions

What is the data rate of the MAX491ECSD+T?

The MAX491ECSD+T supports a maximum data rate of 2.5 Mbps in full-duplex RS-422 or RS-485 mode.
