4000 Series CMOS Logic Chips
Typical Performance (some types vary such as those with unbuffered outputs:
Supply 3 to 15V
Very high input impedance (do not leave inputs floating)
Outputs can sink or source 1mA
One output can drive up to 50 inputs
Gate propergation time 30nS at 9V
Frequency 1MHz
Power consumption - very low, a few micro watts to a few mW at high frequencies
