SOOS038A - JANUARY 1987 - REVISED JULY 1989
The TIL189 and TIL190 Optocouplers are designed for use in applications that require high current transfer ratio and high-voltage isolation between the input and output. The TIL189 has the base connected for applications where a base signal or resistor is required. The TIL190 is designed with no internal base connection for applications where high base-noise immunity is desired. Users can select from four different current gains (TIL189-1 through TIL189-4 and TIL190-1 through TIL190-4).
