CMOS devices have large input impedance with input currents on the order of 0.01nA. Adding feedback circuitry can result in a latch-like device that can be used to store bits, and also operate in a ...
The 74AHC1G02 and 74AHCT1G02 are 2-input NOR gates from the high-speed Si-gate CMOS family. The devices exhibits low power dissipation and high noise immunity for an improved system performance.
