CA-IS3721-Q1 - Automotive High-Speed Dual-Channel Digital Isolators

Download the CA-IS3721-Q1 datasheet PDF. This datasheet also covers the CA-IS3720-Q1 variant, as both devices belong to the same automotive high-speed dual-channel digital isolators family and are provided as variant models within a single manufacturer datasheet.

General Description

The CA‐IS372x‐Q1 devices are high‐performance dual ‐ channel digital isolators with up to 3.75kVRMS (narrow‐ body package) or 5kVRMS (wide‐body package) isolation rating and ultra‐fast data rate.

Key Features

  • Data rate: DC to 150Mbps.
  • Robust isolation barrier.
  • High lifetime: >40 years.
  • Up to 3750 VRMS isolation rating (Narrow body packages) and up to 5000 VRMS isolation rating (Wide body packages).
  • ±150 kV/μs typical CMTI.
  • Wide supply range: 2.5V to 5.5V.
  • Default output High (CA‐IS372xH‐Q1) and Low (CA‐ IS372xL‐Q1) Options.
  • High electromagnetic immunity.
  • No start‐up initialization required.
  • Schmitt trigger inputs.
