Tiny Logic TTL and CMOS digital logic implemented in surface mount, SOT-23 or smaller, cases. Typically 1 or few gates per chip. Many logic families are implemented. Part numbers usually are 74xxx comparable and identified by a …1G…, …2G… or such addition to the part number. 74AUP1G00 would be a single 2-input NAND gate. If anybody shows an interest I will work on a list.
