PHOTOCOUPLER
PS2501-1,-2,-4, PS2501L-1,-2,-4
HIGH ISOLATION VOLTAGE
−NEPOC Series−
SINGLE TRANSISTOR TYPE
MULTI PHOTOCOUPLER SERIES
DESCRIPTION
The PS2501-1, -2, -4 and PS2501L-1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode
and an NPN silicon phototransistor.
The PS2501-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2501L-1, -2, -4 are lead bending type
(Gull-wing) for surface mount.
