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 cou-
pled 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.
