Small-scale integration refers to the first generation of commercial logic chips, typically packing fewer than 100 transistors on a single die. These chips usually provide just a few basic logic gates, flip-flops, or simple amplifiers. While no longer used for complex processing, SSI logic families like the original 7400 series remain in production for basic glue logic and educational purposes.
We can just use a standard SSI quad NAND gate to buffer that signal before it hits the microcontroller.
When troubleshooting vintage electronics, SSI chips are often the easiest to test because their logic functions are simple and well-documented.
