PHOTOCOUPLER
PS2521-1,-2,-4,PS2521L-1,-2,-4
LARGE FORWARD INPUT TYPE
HIGH ISOLATION VOLTAGE
MULTI PHOTOCOUPLER SIRIES
DESCRIPTION
The PS2521-1, -2, -4 and PS2521L-1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode
and an NPN silicon phototransistor.
The PS2521-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2521L-1, -2, -4 are lead bending type
(Gull-wing) for surface mount.
