HCPL3700

The HCPL3700 is a 8-pin DIP AC/DC To Logic Interface Optocoupler 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.

• 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)
