HCPL-3700 A3700 AC/DC To Logic Interface Optocoupler IC DIP-8 Package

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. 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) • VDE certified – ordering option ‘V’, e.g., HCPL3700V Applications:- • Low voltage detection • 5 V to 240 V AC/DC voltage sensing • Relay contact monitor • Current sensing • Microprocessor Interface • Industrial controls Specification:- Symbol Parameter Value Unit TOPR Operating temperature -40 to +85 °C VIN Input Voltage -0.5 (Max.)
