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 compatible.
