Si88641 - QUAD DIGITAL ISOLATORS

Download the Si88641 datasheet PDF. This datasheet also covers the Si88240 variant, as both devices belong to the same quad digital isolators family and are provided as variant models within a single manufacturer datasheet.

General Description

The Si88xx integrates Silicon Labs’ proven digital isolator technology with an on-chip isolated dc-dc converter that provides regulated output voltages of 3.3 or 5.0 V (or >5 V with external components) at peak output power levels of up-to 2 W.

These devices provide up-to four digital channels.

  • Highly-reliable: 100 year lifetime integrated dc-dc converter.
  • High electro-magnetic immunity.
  • Fully-integrated secondary sensing and ultra-low emissions feedback-controlled converter with.
  • RoHS compliant packages dithering for low EMI.
  • SOIC-20 wide body.
  • dc-dc converter efficiency of 78%.
  • Isolation of up to 5000 Vrms.
  • Up to 2 W isolated power with.
  • High transient immunity of integrated power switches 100 k.
