DESCRIPTION
The PS2561-1 is optically coupled isolators containing a GaAs light emitting diode and an NPN silicon
phototransistor.
The PS2561-1 is in a plastic DIP (Dual In-line Package) and the PS2561L-1 is lead bending type (Gull-wing) for
surface mount.
The PS2561L1-1 is lead bending type for long creepage distance.
The PS2561L2-1 is lead bending type for long creepage distance (Gull-wing) for surface mount.
