Silicon Dual Transistor - 1969
TI number: G00332

This was the first dual transistor chips packaged in the 1/4in x 1/4in metal flatpack at TI. The manufacturing date was January, 27 1969. Some of the final fabrication steps were performed by the product engineer, Fritz Whittington.

This work was done on the Lockheed M & S controlled line for the Poseidon Program. This line was operated under rigidly controlled conditions for high reliability. TI had been manufacturing dual transistor since 1963 in the 1/8" x 1/8" metal flatpack for the Minuteman Program. The 1/4" x 1/4" package was chosen for the Poseidon because it was easier to handle and space was available.
