DESCRIPTION
The PS2503-1, -2, -4 and PS2503L-1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode
and an NPN silicon phototransistor.
The PS2503-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2503L-1, -2, -4 are lead bending type
(Gull-wing) for surface mount.
