Data Sheet
PS2505-1, -4, PS2505L-1, -4
HIGH ISOLATION VOLTAGE AC INPUT RESPONSE TYPE
DESCRIPTION
The PS2505-1, -4 and PS2505L-1, -4 are optically coupled isolators containing a GaAs light emitting diodes
and an NPN silicon phototransistor.
The PS2505-1, -4 are in a plastic DIP (Dual In-line Package) and the PS2505L-1, -4 are lead bending type
(Gull-wing) for surface mount.
