HCPL-181 Datasheet | Broadcom

Description The Broad® HCPL-181 contains a light-emitting diode optically coupled to a phototransistor. It is packaged in a 4-pin mini-flat SMD package with a 2.0-mm profile. The small dimension of this product allows significant space saving. The package volume is 30% smaller than that of conventional DIP type. Input-output isolation voltage is 3750 Vrms. Response time, tr, is typically 4 μs and minimum CTR is 50% at input current of 5 m A. Schematic 1 IF ANODE + VF IC 4 COLLECTOR - CATHODE 3 EMITTER Functional Diagram PIN NO.
