Choice of Three Current-Transfer Ratios
description
These optocouplers consist of one gallium-arsenide light-emitting diode and one silicon npn phototransistor per
channel. The TIL191 has a single channel in a 4-pin package, the TIL192 has two channels in an 8-package,
and the TIL193 has four channels in a 16-pin package. The standard devices, TIL191, TIL192, and TIL193, 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.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
