Detailed Description for ST485EBDR
Product Overview
The ST485EBDR from STMicroelectronics is a surface-mount transceiver intended for RS422 and RS485 serial communication links. It combines one driver and one receiver in an 8-SOIC package and operates from a 4.75 V to 5.25 V supply. The device supports half-duplex operation and a 5 Mbps data rate, with 70 mV receiver hysteresis. Its specified operating temperature range is -40°C to 85°C.
Key Features
- RS422 and RS485 protocol support
- 1 driver and 1 receiver
- Half-duplex transceiver operation
- 5 Mbps data rate
- 70 mV receiver hysteresis
- 4.75 V to 5.25 V supply voltage
- -40°C to 85°C operating temperature range
- Surface-mount 8-SOIC package (0.154 inch, 3.90 mm width)
Applications
- Embedded systems requiring RS422 or RS485 serial communication.
- Half-duplex serial links using a single driver and a single receiver.
- Surface-mount interface boards operating from a 4.75 V to 5.25 V supply.
Design & Procurement Notes
When selecting the ST485EBDR, confirm that the system supply stays within 4.75 V to 5.25 V and that the PCB can accommodate the surface-mount 8-SOIC footprint. Because the device is a 1/1 half-duplex transceiver, the link architecture should account for shared transmit and receive timing rather than simultaneous full-duplex operation. Verify that the required link speed is at or below 5 Mbps and that the 70 mV receiver hysteresis is appropriate for the expected signal quality. The -40°C to 85°C operating range should also be checked against the actual ambient conditions of the end product.
