Product Overview

The ISO7420MD is a dual-channel Digital Isolator provide galvanic isolation up to 2500VRMS for 1 minute per UL. This isolator has two isolated channels. Each isolation channel has a logic input and output buffer separated by a silicon dioxide (SiO2) insulation barrier. Used in conjunction with isolated power supplies, this device prevents noise currents on a data bus or other circuit from entering the local ground and interfering with or damaging sensitive circuitry. It has TTL input thresholds and require two supply voltages, 3.3 or 5V or any combination. All inputs are 5V tolerant when supplied from a 3.3V supply. It is specified for signalling rates up to 1Mbps. Due to their fast response time, under most cases, these devices will also transmit data with much shorter pulse widths. Designers should add external filtering to remove spurious signals with input pulse duration <20ns if desired.
  • Low power consumption
  • 1Mbps Highest signalling rate
  • 300ps Typical low skew
  • 50kV/µs Typical transient immunity
  • Over 25-year isolation integrity at rated voltage
  • 2500 VRMS Isolation for 1 minute per UL 1577
  • Green product and no Sb/Br

Applications

Industrial, Communications & Networking, Motor Drive & Control, Power Management

Warnings

Device has limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
