The OPF2412 family is a low cost digital output fiber optic receiver. The lensed optical system keeps the receiver response
consistent for all fiber sizes which makes it idea for use on fibers as small as 50/125µm. The design incorporates a monolithic
photo-IC comprised of a photodetector and DC amplifier driving an open collector output Schottky transistor. The output makes
the OPF2412 compatible with TTL and CMOS logic. The receiver is designed to operate from a single +5 V supply. A bypass
capacitor (0.1µF ceramic) should be connected from VCC to GND of the receiver.
