Yes, both.  However, if your question really is "is their power consumption
very low?", you had better ask that explicitly.  There's CMOS, and then
there's CMOS.  Most modern microprocessors, some of which run too hot to
touch, are CMOS -- they'd melt if they were NMOS.  CMOS technology is
used in many parts which are not "classical" ultra-low-power CMOS.

The MAX232 pulls 5-10 mA with no load.  I haven't got a 145407 datasheet
handy.
