The lensed optical system keeps the receiver response consistent for all fiber sizes which makes it ideal for use on fibers as small as 50/125|mm. The OPF2412 contains 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 (0.1 | F ceramic) should be connected from Pin 2 (VCC) to Pin 3 (Common) of the receiver. *ST is a registered trademark of AT&T. 2 v, ce B DATA 3 & 7 COMMON PIN FUNCTION 1** N.C. 2 Vcc(5V) 3* Common 4** N.C. 5** N.C. 6 Data 7* Common 8** N.C.
