DESCRIPTION
The PS9121 is an optically coupled high-speed, active low type isolator containing a GaAlAs LED on the input side and a photodiode and a signal processing circuit on the output side on one chip. The PS9121 is designed specifically for high common mode transient immunity (CMR) and low pulse width distortion. The PS9121 is suitable for high density application.

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.)
• Small package (SO-5)
• High-speed (15 Mbps)
• High isolation voltage (BV = 3 750 Vr.m.s.)
• Open collector output
