MAX1482 - Slew-Rate-Limited RS-485 Transceivers

Description

The MAX1482 and MAX1483 are low-power transceivers for RS-485 and RS-422 communication.

Both feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables.

Data rates are guaranteed up to 250kbps.

Features

  • Low 20µA Operating Current.
  • Slew-Rate Limited for Reduced EMI and Reduced Reflections.
  • 0.1µA Low-Current Shutdown Mode.
  • Designed for RS-485 and RS-422.

19-0367; Rev 1; 5/06 MAX1482/MAX1483 20µA, 1⁄8-Unit-Load, Slew-Rate-Limited RS-485 Transceivers _______________General Description The MAX1482 and MAX1483 are low-power transceivers for RS-485 and RS-422 communication. Both feature slew-rate-limited drivers that minimize EMI and reduce reflections caused by improperly terminated cables. Data rates are guaranteed up to 250kbps. The MAX1482/MAX1483 draw only 20µA of supply current. Additionally, they have a low-current shutdown mode that consumes only 0.1µA. Both parts operate from a single +5V supply. Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-impedance state.
