SINGLE CHANNEL IL766 DUAL CHANNEL ILD766 Bidirectional Input Darlington Optocoupler FEATURES * Internal RBE for Better Stability * High Current Transfer Ratios, VCE=5.0 V IL/ILD766-1: 500% at IF=2.0 mA IL/ILD766-2: 500% at IF=1.0 mA * BVCEO >60 V * AC or Polarity Insensitive Inputs * Built-In Reverse Polarity Input Protection * Industry Standard DIP Package * Underwriters Lab File #E52744 DESCRIPTION The IL/ILD766 are bidirectional input optically coupled isolators. They consist of two Gallium Arsenide infrared emitting diodes coupled to a silicon NPN photodarlington per channel. The IL766 are single channel optocouplers. The ILD766 has two isolated channels in a single DIP package. They are designed for applications requiring detection or monitoring of AC signals.
