SN502 Solid Circuit Flip Flop

It was introduced by TI in March, 1960, as the SN502 Solid Circuit Flip Flop. The initial price was $450 each.

For the package, the frame, leads and base were assembled with glass frit. The kovar lid was soldered in place. From a discussion with Jack Kilby, the difference in package lead configuration between this device and the G00013 was due to this being an earlier prototype device. The March, 1960, catalog data sheet shows the lead configuration of G00013.
