DESCRIPTION
The PS2561-1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode and an NPN silicon phototransistor.
The PS2561-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2561L-1, -2, -4 are lead bending type (Gull-wing) for surface mount.
The PS2561L1-1, -2, -4 are lead bending type for long creepage distance.
The PS2561L2-1, -2, -4 are lead bending type for long creepage distance (Gull-wing) for surface mount.
