CS48505A - 3.0V to 5.5V RS485/RS422 Transceivers

General Description

The CS485xxA family of devices are low-power half-duplex transceivers for RS-485/RS-422 communications in harsh environments.

All devices feature ±20kV electro-static discharge (ESD) protection for the bus pins (A and B), eliminating the need for additional system level protection components.

Key Features

  • High-Performance and Compliant with RS-485 EIA/ TIA-485 Standard.
  • Low EMI 500kbps Data Rate (CS48505Ax) and up to 20Mbps (CS48520Ax) High-Speed Data Rate.
  • 1/8 Unit Load Enables up to 256 Nodes on the Same Bus.
  • Integrated Protection for Robust Communication.
  • -7V to +12V Common-Mode Voltage Range.
  • ±20kV Human Body Model ESD Protection and ±6kV Contact Discharge IEC 61000-4-2 ESD Protection on A/B pins.
  • Short-Circuit Protection.
  • Thermal Shutdown.
