PHOTOCOUPLER
PS2561-1,-2, PS2561L-1,-2
HIGH ISOLATION VOLTAGE
SINGLE TRANSISTOR TYPE
MULTI PHOTOCOUPLER SERIES
DESCRIPTION
The PS2561-1, -2 and PS2561L-1, -2 are optically coupled isolators containing a GaAs light emitting diode and an
NPN silicon phototransistor.
PS2561-1, -2 are in a plastic DIP (Dual In-line Package) and PS2561L-1, -2 are lead bending type (Gull-wing) for
surface mount.
