Product Overview

The ISO7220BD is a dual-channel Digital Isolator to facilitate PCB layout, the channels are oriented in the same direction. It has a logic input and output buffer separated by TI's silicon-dioxide (SiO2) isolation barrier, providing galvanic isolation of up to 4000 VPK per VDE. Used in conjunction with isolated power supplies, this device block high voltage and isolate grounds, as well as prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. A binary input signal is conditioned, translated to a balanced signal and then differentiated by the capacitive isolation barrier. Across the isolation barrier, a differential comparator receives the logic transition information, then sets or resets a flip-flop and the output circuit accordingly. A periodic update pulse is sent across the barrier to ensure the proper dc level of the output.
  • 1ns Maximum low channel-to-channel output skew
  • 1ns Maximum low pulse-width distortion (PWD)
  • 1ns Typical at 150Mbps low jitter content
  • 50kV/µs Typical transient immunity
  • 4kV ESD Protection
  • High electromagnetic immunity (EMI)
  • Green product and no Sb/Br
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.
