2561 Datasheet PDF



The 2561 is an optically coupled isolator containing a GaAs light emitting diode and an NPN silicon phototransistor to realize an excellent cost performance. The PS2561A-1 is in a plastic DIP (Dual In-line Package) and the PS2561AL-1 is lead bending type (Gull-wing) for surface mount. The PS2561AL1-1 is lead bending L1 type and the PS2561AL2-1 is lead bending L2 type (Gull-wing).
