Littelfuse, Inc. Power Semiconductors & Control ICs - Integrated Circuits - Optocouplers - Series: Dual Optocouplers - LDA212 LDA212

Single and dual OptoMOS® products provide an optically isolated means of switching control circuits. Each package contains one or two phototransistors that are optically coupled with LEDs. Shunt resistors can be used to adjust the threshold current required to activate the output circuitry. The LDA contains sensors that allow for either AC or DC input circuits and single transistor or Darlington transistor outputs. Single and dual optocouplers are ideal for Telecom, Industrial Control and instrumentation circuits, where electrical isolation of control circuitry is crucial. Ac and dc input versions Machine-insertable and wave-solderable
