Complementary transistor-transistor logic /CTTL/ - An approach to high-speed micropower logic.
Description of a new approach to micropower integrated circuits that is called complementary transistor-transistor logic (CTTL). This logic combines the inherent low standby power of a complementary inverter with the high speed of the TTL-type input. Results of monolithic fabricated circuits are presented. These circuits are shown to be equally adaptable to hybrid and discrete circuitry.
