Description
TIL198B Texas Instruments Transistor Output Optocouplers Dual-Channel Optocoupler/Optoisolator 8-PDIP
These optocouplers consist of a gallium-arsenide light-emitting diode and a silicon n-p-n Darlington phototransistor per channel. The TIL197 has one channel in a 4-pin package, the TIL198 has two channels in a 8-pin package, and the TIL199 has four channels in a 16-pin package. The standard devices, TIL197, TIL198, and TIL199, are tested for a current-transfer ratio of 500% minimum. Devices selected for a current-transfer ratio of 1000% and 1500% minimum are designated with the suffixes A and B, respectively.
