PHOTOCOUPLER
PS2503-1,PS2503L-1
LOW INPUT CURRENT, HIGH SPEED SWITCHING
MULTI PHOTOCOUPLER SERIES
NEPOC Series
DESCRIPTION
The PS2503-1 and PS2503L-1 are optically coupled isolators containing a GaAs light emitting diode and an NPN
silicon phototransistor.
The PS2503-1 is in a plastic DIP (Dual In-line Package) and the PS2503L-1 is lead bending type (Gull-wing) for
surface mount.
