TIDA-00060 Reference Design

Texas Instruments

Extended Common-mode Range RS-485 Reference Design

Description

This reference design provides a 500kbps 5V RS-485 interface using the SN65HVD22 extended common-mode RS-485 transceiver.   The extended -20 V to 25 V Common-Mode Voltage Range: more than double the TIA/EIA-485 requirement: providing robust signal integrity and enabling use in long cable networks

Features
  • Wide common-mode range (-20V to 25V) enables use in long cable networksMore than 100mV receiver hysteresis - highly reliable in harsh environmentsLow standby current: 1uA maxFailsafe receiver for open circuit: short circuit: and idle-bus conditionsThis reference design is orderable
Applications
  • Telehealth systems
