This datasheet also covers the CS485 variant, as both devices belong to the same 3.0v to 5.5v rs485/rs422 transceivers family and are provided as variant models within a single manufacturer datasheet.
General 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.
Key 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.
