| IL755 DUAL CHANNEL ILD755 SINGLE CHANNEL BIDIRECTIONAL INPUT DARLINGTON OPTOCOUPLER FEATURES * High Current Transfer Ratios, VCE=5 V IL/ILD755-1: 750% at IF=2 mA * IL/ILD755-2: 1000% at IF=1 mA BVCEO >60 V * AC or Polarity Insensitive Inputs * Built-In Reverse Polarity Input Protection * Industry Standard DIP Package * Underwriters Lab File #E52744 * VDE #0884 Available with Option 1 DESCRIPTION The IL/ILD755 are bidirectional input optically coupled isolators. They consist of two Gallium Arsenide infrared emitting diodes coupled to a silicon NPN photodarlington per channel. The IL755 are single channel Darlington optocouplers. The ILD755 has two isolated channels in a single DIP package. They are designed for applications requiring detection or monitoring of AC signals.
