| www..com K814P/ K824P/ K844P Vishay Telefunken Optocoupler with Phototransistor Output Description The K814P/ K824P/ K844P consist of a phototransistor optically coupled to 2 gallium arsenide infrared-emitting diodes (reversed polarity) in an 4-lead up to 16-lead plastic dual inline package. The elements are mounted on one leadframe using a coplanar technique, providing a fixed distance between input and output for highest safety requirements. Applications Feature phones, answering machines, PABX, fax machines Coll. Emitter 14925 Features D Endstackable to 2.54 mm (0.1') spacing D Low coupling capacitance of typical 0.3 pF D Current Transfer Ratio (CTR) of typical 100% D Low temperature coefficient of CTR D Wide ambient temperature range D Underwriters Laboratory (UL) 1577 recognized, file number E-76222 D CSA (C-UL) 1577 recognized, file number E-76222 - Double Protection D Coupling System U Anode Cath. 4 PIN 8 PIN 16 PIN 13947 D DC isolation test voltage VIO = 5 kV C Order Instruction Ordering Code K814P K824P K844P CTR Ranking < 20% < 20% < 20% Remarks 4 Pin Single channel 8 Pin Dual channel 16 Pin Quad channel Rev.
