FAIRCHILD H11AA1M H11AA2M H11AA3M H11AA4M AC Input/Phototransistor Optocouplers handbook
The document describes the H11AAXM series of AC Input/Phototransistor Optocouplers manufactured by Fairchild Semiconductor. These devices consist of two gallium-arsenide infrared emitting diodes connected in inverse parallel, driving a single silicon phototransistor output. Key features include bi-polar emitter input and built-in reverse polarity input protection.
