CS485M - 3.0V to 5.5V RS485/RS422 Transceivers

This page provides the datasheet information for the CS485M, a member of the CS485 3.0V to 5.5V RS485/RS422 Transceivers family.

Datasheet Summary

Description

The CS485 family of devices are low-power half-duplex transceivers for RS-485/RS-422 communications in harsh environments.

All devices feature ±18kV electro-static discharge (ESD) protection for the bus pins (A and B), eliminating the need for additional system level protection components.

Features

  • High-Performance and Compliant with RS-485 EIA/ TIA-485 Standard.
  • Low EMI 250kbps Data Rate.
  • Allow up to 50 Nodes on the Same Bus.
  • Integrated Protection for Robust Communication.
  • -7V to +12V Common-Mode Voltage Range.
  • ±18kV Human Body Model ESD Protection and ±4kV Contact Discharge IEC 61000-4-2 ESD Protection on A/B pins.
  • Short-Circuit Protection.
  • Thermal Shutdown.
  • True Fail-Safe Guarantees Known Receiver Output State.
  • Glitch-free durin.
