ST485EB

Description

SO-8 Driver is short-circuit current limited and is protected against excessive power dissipation by thermal shutdown circuitry that place the driver outputs into a high-impedance state. The ST485E is designed for bi-directional data communications on multipoint bus transmission lines (half-duplex applications).

Key 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 (HBM) - ± 8 kV (IEC-1000-4-2 contact discharge)
  • Allows up to 256 transceivers on the bus
