Product Introduction

Ultra-low-power digital isolators are CMOS devices offering substantial data rate, propagation delay, power, size, reliability, and external BOM advantages when compared to legacy isolation technologies. The operating parameters of these products remain stable across wide temperature ranges throughout their service life. For ease of design, only VDD bypass capacitors are required.

Data rates up to 150 Mbps are supported, and all devices achieve worst-case propagation delays of less than 10 ns. All products are safety certified by UL, CSA, and VDE and support withstand voltages of up to 2.5 kVrms. These devices are available in an 8-pin narrow-body SOIC package.

Features

  • High-speed operation Up to 2500 VRMS isolation
  • DC to 150 Mbps
  • 60-year life at rated working
  • No start-up initialization required voltage
  • Wide Operating Supply Voltage: 2.70–5.5 V
  • Precise timing (typical) <10 ns worst case
  • Ultra low power (typical)
  • 5 V Operation: <2.1 mA per channel at 1 Mbps; <6 mA per channel at 100 Mbps
  • 2.70 V Operation: <1.8 mA per channel at 1 Mbps; <4 mA per channel at 100 Mbps
  • 1.5 ns pulse width distortion
  • 0.5 ns channel-channel skew
  • 2 ns propagation delay skew
  • 6 ns minimum pulse width
  • Transient Immunity 25 kV/µs
  • Wide temperature range -40 to 125 °C at 150 Mbps
  • High electromagnetic immunity
  • RoHS-compliant packages: SOIC-8 narrow body
