DESCRIPTION
The PS2505-1, -2, -4 and PS2505L-1, -2, -4 are optically coupled isolators containing GaAs light emitting diodes
and an NPN silicon phototransistor.
The PS2505-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2505L-1, -2, -4 are lead bending type
(Gull-wing) for surface mount.
FEATURES
• AC input response
• High isolation voltage (BV = 5 000 Vr.m.s.)
• High collector to emitter voltage (V
CEO
= 80 V)
• High-speed switching (t
