DESCRIPTION
PS2603, PS2604 ,PS2603L and PS2604L are optically coupled isolators containing a GaAs light emitting diode and an NPN silicon Darlington-connected phototransistor. PS2603 and PS2604 are in a plastic DIP (Dual In-line Package). PS2603L and PS2604L are lead bending type (Gull-wing) for surface mount. PS2603 and PS2603L have a base pin, PS2604 and PS2604L have no base pin.
