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. -- 1972: Saturn V #15 flight-ready| Henry Spencer at U of Toronto Zoology 1990: birds nesting in engines | uunet!attcan!utzoo!henry henry@zoo.toronto.edu
