Introduction
The SP3485E is a 3.3V, half-duplex, low-power transceiver for RS-485/RS-422 communications, fully compliant with the TIA/EIA-485 standard. The device integrates one driver and one receiver, each independently enable or disable controlled, presenting a high-impedance state when disabled. The receiver features 1/8 unit load high input impedance, supporting up to 256 transceivers connected in parallel on the same bus, enabling error-free data transmission at up to 12Mbps. Operating supply voltage ranges from 3.0V to 3.6V, with integrated failsafe, over-temperature protection, current-limiting protection, and overvoltage protection, ensuring reliable communication in electrically noisy environments.
Features
- 3.3V supply, half-duplex architecture
- 1/8 unit load, supports up to 256 devices in parallel on the bus
- Driver with short-circuit output protection
- Integrated over-temperature protection
- Low-power shutdown mode support
- Receiver with open-circuit failsafe protection
- Robust noise immunity
- Integrated transient voltage suppression
- Data rate up to 12Mbps in electrically noisy environments
