HCPL-3700

AC/DC TO LOGIC INTERFACE OPTOCOUPLER HCPL-3700 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 compatible. 8 1 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 APPLICATIONS Low voltage detection 5 V to 240 V AC/DC voltage sensing Relay contact monitor Current sensing Microprocessor Interface Industrial controls A 0.1 µF bypass capacitor must be connected between pins 8 and 5.
