Detailed Description for ST3485EBDR
Product Overview
The ST3485EBDR from STMicroelectronics is a half-duplex RS422 and RS485 transceiver in an 8-SOIC surface-mount package. It provides one driver and one receiver for differential serial communication at data rates up to 15Mbps. This configuration supports single-channel differential serial links. The device operates from a 3V to 3.6V supply and includes 70mV receiver hysteresis. Its specified operating temperature range is -40°C to 85°C, and it carries AEC-Q100 qualification.
Key Features
- Half-duplex RS422 and RS485 transceiver with one driver and one receiver
- Supports data rates up to 15Mbps
- 3V to 3.6V supply voltage
- 70mV receiver hysteresis
- Operating temperature range of -40°C to 85°C
- 8-SOIC surface-mount package with 0.154 in, 3.90 mm width
- AEC-Q100 qualified
Applications
- Differential serial communication links in control and instrumentation systems
- Half-duplex RS422 and RS485 interface nodes
- Embedded boards using 3V to 3.6V supply rails
Design & Procurement Notes
Designers should verify that the system supply remains within 3V to 3.6V across load and temperature variations. The 8-SOIC package supports surface-mount assembly, and the 0.154 in, 3.90 mm width should be checked against the board footprint and spacing. Because the device is half duplex with one driver and one receiver, direction control and bus turnaround timing must be managed by the system design. The 70mV receiver hysteresis should be considered when evaluating differential input signal quality at the 15Mbps data rate. The -40°C to 85°C range and AEC-Q100 qualification should be checked against design requirements.
