Integrated Circuits

The 7400 family of small-scale integrated circuits came in 14-pin packages with two rows of 7 pins each; one row on each side. Here are some examples:

7400 Quad 2-Input NAND Gates 7400
7402 Quad 2-Input NOR Gates 7402
7404 Six Inverters 7404
7410 Triple 3-Input NAND Gates 7410
