Si84xx Digital Isolators​​

Note: The Silicon Labs Si84xx devices remain in production, but are not recommended for new designs. For new designs, please use the Si86xx Digital Isolators instead.

The Silicon Labs Si84xx digital isolator family is the industry’s highest-performance, easiest-to-use, and lowest-cost line of 2.5 to 5.0 kVrms rated digital isolators. These digital isolators are 10x more reliable than optocouplers.

Features

  •  5 kV, 2.5 kV and 1 kV isolation ratings
  • High integration: up to 6 isolation channels in a single package
  • High-speed operation: DC–150 Mbps
  • Wide operating supply voltage: 2.7 - 5.5 V
  • Low power consumption
  • Precise timing
  • Less than 10 ns propagation delay
  • 2 ns pulse width distortion
  • 1 ns channel-channel matching
  • 2 ns pulse width skew
  • Transient immunity: >25 kV/µs
  • Enable controlled outputs
  • DC correct
  • No start-up initialization required
