MDRI485x

MDRI485x series are RS-485/422 interface transceivers intended for half-duplex communication channel according standard RS-485/422.

Main features:

  • maximum data rate:
  • MDRI4851 500 kbps
  • MDRI4852 2500 kbps
  • for MDRI4851: the transmitter outputs are slew rate limited to reduce EMI and reflections from improperly terminated buses
  • the chips have a 1/8 unit load (1/8 U.L.) receiver input impedance that allows up to 256 parallel equivalent transceivers on a bus
  • fail-safe operation when the receiver inputs are short-circuit or open-circuit. No external fail-safe resistors are demanded
  • hot-swap mode prevents transmitter/receiver output false-switching when power-on
