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 con-
trolling threshold levels over a wide range of input voltages with a single resistor.
The output is TTL and CMOS compatible.
