The PS9821-1 and PS9821-2 are active-low type high-speed photocouplers that use a GaAlAs light-emitting diode on the input side and a photodetector IC that includes a photodiode and a signal processor on the same chip on the output side. The PS9821-1, -2 are designed specifically for high common mode transient immunity (CMR) and low pulse width distortion, PS9821-2 is suitable for high density applications.

Features

  • Low power consumption (VCC = 3.3 V)
  • Pulse width distortion (⏐tPHL−tPLH⏐ = 35 ns MAX.)
  • High common mode transient immunity (CMH, CML = ±15 kV/μs MIN.)
  • 40% reduction of mounting area (5-pin SOP × 2)
  • High-speed (15 Mbps)
  • High isolation voltage (BV = 2 500 Vr.m.s.)
  • Open collector output
