Low Power Schottky (LSTTL) has become the industry standard logic in recent years, replacing the original 7400 TTL with lower power and higher speeds. In addition to offering the standard LS TTL circuits, Motorola offers the FAST Schottky and TTL family. Complete specifications for each of these families are provided in data sheet form. Functional selector guides not only provide an overview of already introduced devices but planned introduction dates of new products. .......

Lattice is the source for innovative FPGA, PLD, programmable Power Management and Clock Management solutions. The LatticeECP3 family defines a new mid-range, value-based class of FPGAs, not only by further reducing costs, but also by reducing static power consumption by up to 80% and total power consumption by over 50% for typical designs, compared to competitive SERDES-capable FPGAs. The MachXO family of non-volatile, infinitely reconfigurable PLD devices is designed for applications tradition.......
