概要

The RAA7884QR is a ±16.5kV IEC61000-4-2 ESD protected, 3.0V to 5.5V powered, quad receiver designed for balanced communication using the RS-485 and RS-422 standards. With low input currents (±200µA), the receiver presents a 1/4 unit load to the RS-485 bus and allows up to 128 receivers on the bus.

The RAA7884QR is a high data rate receiver that operates at data rates up to 80Mbps. With an 8ns maximum propagation delay skew (tolerance), it ensures excellent part-to-part matching. The receiver outputs are tri-statable and include a hot plug feature to keep them disabled during power-up and power-down.

  • IEC61000 ESD protection (RS-485 inputs): ±16.5kV
    • Class 3 ESD on all other pins: >8kV HBM
  • Wide supply range: 3.0V to 5.5V
  • Wide common-mode range: -7V to +12V
  • Low part-to-part propagation delay tolerance: 8ns (maximum)
  • Specified for +125°C operation
  • Fail-safe open Rx inputs
  • 1/4 unit load allows 128 devices on the bus
  • Available in industry standard pinout
  • High data rate of up to 80Mbps
  • Low shutdown supply current: 15µA
  • Tri-statable Rx outputs
  • 5V tolerant logic inputs when VCC = 3.3V
  • RoHS Compliant
