DESCRIPTION

NEC’s PS9821 is an optically coupled high-speed isolator containing a GaAlAs LED on the input side and a photodiode and a signal processing circuit on the output side on one chip.

FEATURES

  • Supply Voltage 3.3V
  • Open collector output
  • High common mode transient immunity (CMH, CML = ±15 kV/µs Min.)
  • Small package (SO8)
  • High-speed (10 Mbps)
  • High isolation voltage (BV = 2 500 Vr.m.s.)

APPLICATIONS

  • Factory Automation Network
  • Measurement equipment
