HCPL-3700 Datasheet AC/dc To Logic Interface Optocoupler

Manufacturer: Fairchild (now onsemi)

Overview: AC/DC TO LOGIC INTERFACE OPTOCOUPLER HCPL-3700.

General Description

The HCPL-3700 voltage/current threshold detection optocoupler consists of an AlGaAs LED connected to a threshold sensing input buffer IC which are optically coupled to a high gain darlington output.

The input buffer chip is capable of controlling threshold levels over a wide range of input voltages with a single resistor.

The output is TTL and CMOS patible.

Key Features

  • AC or DC input Programmable sense voltage Logic level compatibility Threshold guaranteed over temperature (0°C to 70°C).
  • Optoplanar™ construction for high common mode immunity.
  • UL recognized (file # E90700) TRUTH TABLE (Positive Logic) Input H L Output L H 8 1 8 1.
