Logic Output Optocouplers
FAIRCHILD [Fairchild Semiconductor]


The  HCPL3700SDV  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.
