description

The TIL187 and TIL188 Optocouplers are designed for use in AC applications that require very high current transfer ratio and high voltage isolation between input and output. These optocouplers consist ot two GaAs light-emitting diodes connected in a reverse-parallel configuration and a silicon n-p-n Darlington phototransistor. The TIL187 has the base connected for applications where a base signal or base resistor is required. The TIL188 is designed with no base connected for applications where high base-noise immunity is desired. Users can select from four different current gains (TIL187-1 through TIL187-4 and TIL188-1 through TIL188-4).
