The PS9117A 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 PS9117A is designed specifically for high common mode transient immunity (CMR) and low pulse width distortion. The PS9117A is suitable for high density application.
The PS9117A is a high‑speed, active‑low type optically coupled isolator that integrates a GaAlAs LED, photodiode and signal‑processing circuit on a single chip. It offers high common‑mode transient immunity, low pulse‑width distortion, and a small 5‑pin SOP package suitable for high‑density applications.
The sheet lists absolute maximum ratings, recommended operating conditions, electrical characteristics, and typical performance graphs. Ordering information, safety approvals (UL and DIN), and handling cautions are also included to aid designers in selecting and integrating the device.
