Normal optical input levels to the receiver result in a
logic “1” output, asserted. Low input levels to the
receiver result in a fault condition indicated by a logic
“0”output, deasserted.
Receiver Power Supply ,provide +5V(+3.3V) a the
5 VccR
recommended receiver power supply filter circuit.
Locate the power filter circuit as close as possible to
the VCCT pin
Transmitter Power Supply, provide +3.3V /+5V DC
