How does the 4000 series of CMOS logic compare in terms of speed and power dissipation to the standard family of TTL logic?

less power dissipation and slower speed

more power dissipation and slower speed

more power dissipation and faster speed

less power dissipation and faster speed

Why is the operating frequency for CMOS devices critical for determining power dissipation?

At high frequencies, charging and discharging the gate capacitance will draw a heavy current from the power supply and thus increase power dissipation.

At low frequencies power dissipation increases.

At high frequencies the gate will only be able to deliver 70.7 % of rated power.
