SP4082E - 5V RS-485/RS-422 Transceivers

General Description

The SP4082E is designed for reliable, bidirectional communication on multipoint bus transmission lines.

The device contains one differential driver and one differential receiver.

It is a half-duplex device.

Key Features

  • 5.0V single supply operation.
  • Receiver failsafe on open or shorted lines.
  • 1/8th Unit Load, 256 transceivers on bus.
  • Robust ESD protection for RS-485 pins ±15kV Human Body Model.
  • Controlled driver slew rates 115kbps, Low EMI.
  • Driver short circuit current limit and thermal shutdown for overload protection.
  • Industry standard package footprints RO 1 RE 2 DE 3 DI 4 8 PIN NSOIC SP4082E Half Duplex 8 Vcc 7B 6A 5 GND.
