The 2147s draw a lot more power than the 4044s
Well, there are lower consumption parts available; the Intel 2147L or
C2147AL; the AMD Am21L47. On the other hand, if you've got the
supply headroom, the 2147 is only 2 bucks and change at Arcade
Components.
But good luck finding the low-power variety.
