description
These optocouplers consist of two gallium-arsenide light-emitting diodes connected in a reverse-parallel
configuration for ac-input applications and a silicon n-p-n phototransistor per channel. The TIL920 has one
channel in a 4-pin package, the TIL921 has two channels in an 8-pin package, and the TIL922 has four channels
in a 16-pin package. The standard devices, TIL920, TIL921, and TIL922, are tested for a current-transfer ratio
of 20% minimum. Devices selected for a current-transfer ratio of 50% and 100% minimum are designated with
the suffix A and B respectively.
