STMicroelectronics | ST485EBDR

The ST485EBDR is a part of ST485 series Transceiver. It has an operating temperature ranging from -40 °C to +85 °C and it comes in SOIC-8 Packaging.

The ST485E is a low power transceiver for RS-485 and RS-422 communication. Each driver output and receiver input is protected against ±15 kV electrostatic discharge (H.B.M.) (ESD) shocks, without latch-up. These parts contain one driver and one receiver in half duplex configuration.

Features:

• Low quiescent current: 300 µA
• Designed for RS-485 interface application
• -7 V to 12 V common mode input voltage range
• Driver maintains high impedance in 3-state or with the power OFF
• 70 mV typical input hysteresis
• 30 ns propagation delay, 5 ns skew
• Operates from a single 5 V supply
• Current limiting and thermal shutdown for driver overload protection
• ESD protection:
  • ±15 kV (H.B.M.)
  • ±8 kV (IEC-1000-4-2 contact discharge)
• Allows up to 256 transceivers on the bus
