Semiconductor Logic Device

Cross-Reference Here is a comprehensive cross-reference of TTL and CMOS chips that are readily available over the counter ( from such places as Maplin Electronics in the UK ). Tables of both TTL and CMOS devices are provided along with tables grouping chips with the same functionality together. The following tables are available ... TTL Device Summary CMOS Device Summary NAND Gates NOR Gates AND Gates OR Gates XOR Gates Buffers Inverters Interface Devices Counters Latches and Flip-Flops Decoders Encoders Shift Registers Computational Devices Monostables and Multivibrators Analogue Switches Miscellaneous Functions

Please note that although the descriptions of the chips are taken from manufacturer's data sheets and other sources; these descriptions are only a brief indication of the generic functionality of that chip and a particular chip may have functionality that is slightly different to that actually required. Before using any device in the design or implementation of a project; always consult the original manufacturer's data sheet to ensure that a particular device is suitable for your purposes.
