ISO7421 - Low-Power Dual-Channel Digital Isolators

Download the ISO7421 datasheet PDF (ISO7420 included). The manufacturer datasheet provides complete specifications, pinout details, electrical characteristics, and typical applications for low-power dual-channel digital isolators.

Description

The ISO7420, ISO7420M and ISO7421 provide galvanic isolation up to 2500 VRMS for 1 minute per UL.

These digital isolators have two isolated channels.

Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier.

Features

  • Low Power Consumption, Typical ICC per Channel (3.3-V operation):.
  • ISO7420: 1.1 mA, ISO7421: 1.5 mA.
  • Low Propagation Delay.
  • 9 ns Typical.
  • Low Skew.
  • 300 ps Typical.
  • Wide TA Range:.
  • 40°C to 125°C (M-Grade).
  • 50-kV/μs Transient Immunity, Typical.
  • Over 25-Year Isolation Integrity at Rated Voltage.
  • Operates From 3.3-V and 5-V Supply and Logic Levels.
  • 3.3.
