This data sheet provides detailed information on the PS9821-1 and PS9821-2 high CMR, 15 Mbps open collector output type 8-pin SSOP (SO-8) 3.3V high-speed photocouplers.
The PS9821‑1 and PS9821‑2 are active‑low type high‑speed photocouplers that use a GaAlAs LED on the input side and an integrated photodetector on the output side. They are designed for high common‑mode transient immunity (CMR) and low pulse‑width distortion, with the PS9821‑2 optimized for high‑density applications.
The data sheet provides package dimensions, pin assignments, absolute maximum ratings, recommended operating conditions, and full electrical characteristics such as isolation voltage, propagation delay, and power dissipation. Ordering information, safety approvals (UL, DIN EN60747‑5‑2) and usage cautions are also included.
