At 250 kbps, this transceiver is sized for Profibus DP at the lower baud rate or Modbus RTU. It is not a high-speed part for backplanes; the 250 kbps ceiling keeps EMI low and allows longer cable segments without repeaters. The 100 mV hysteresis helps prevent false triggering from ground shifts or coupled noise on unshielded twisted pair.
Store the reels in dry storage per JEDEC MSL level — the 8-SOIC package is moisture-sensitive if left unsealed.
The MAX13081EESA+ is rated for 250 kbps data rate, suitable for Profibus DP at lower baud rates, Modbus RTU, and DMX512 applications.
The MAX13082EESA+ is a half-duplex variant; the MAX13081EESA+ is full-duplex. Both operate at 250 kbps in the same 8-SOIC package and 5V supply range. Choose the MAX13081 for four-wire full-duplex links, the MAX13082 for two-wire half-duplex multidrop buses.
No, the MAX13081EESA+ requires a 4.5V to 5.5V supply. It is not rated for 3.3V operation. For 3.3V RS-485 designs, consider the MAX13085EESA+ or similar 3.3V-rated transceivers.
