SIEMENS FEATURES * Internal Rigg for Better Stability High Current Transfer Ratios, Vee=5 V WALD766-1; 500% at I-=2 mA ILALD766-2: 500% at [p=1.0 mA BV cep > 80 AC or Polarity Insensitive Inputs Bulit-In Reverse Polarity Input Protection Industry Standard DIP Package Underwriters Lab Fite #E52744 DESCRIPTION The IL/ILD766 are bidirectional input optically coupled isciators. They consist of two Gallium Arsenide infrared emitting diodes coupled to a silicon NPN photodarlington per channel. The IL766 are singla channel optocouplers. The ILD766 has two isolated channels in a single DIP package. Thay are designed for applications requiring detection or monitoring of AC signals.
