CS485 Shanghai Chipanalog Microelectronics Co., Ltd. Version 1.00, 2022/04/28 3.0V to 5.5V RS485/RS422 Transceivers with ±18kV ESD Protection 1. 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 during Power on/Power off Low Power  Low Supply Current (0.95mA, typ.)  Shutdown Current < 5µA 3V to 5.5V Supply Voltage Range Wide Operating Temperature Range: –40°C to 125°C 8 pin SOIC and 8 pin MSOP Packages 2. Applications • • • • • • • Factory Automation & Control Grid Infrastructure Home and Building Automation Video Surveillance Smart Meters Process Control Telecommunication Equipment • • The CS485 family of devices contain one driver(TX) and one receiver(RX), operates over the +3.0V to +5.5V supply range, making these devices convenient for designers to use one part with either +3.3V or +5V supply systems. These devices are specified for data rates up to 250kbps, also include failsafe circuitry, guaranteeing a logic-high receiver output when the receiver inputs are shorted or open. All devices are specified over the -40°C to +125°C wide operating temperature range and are available in small 8pin MSOP package for space constrained applications and 8-pin SOIC for drop-in compatibility design. Device Information Part number Package Package size (NOM) CS485S SOIC8 4.9mm × 3.9mm CS485M MSOP8 3mm × 3mm Simplified Block Diagram VCC 8 RO REB DE 3. 1 2 7 3 6 B A 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.
