These "LS" chips are basically low power drain CMOS versions of the TTL range. Please note, we do not stock all the listed chips on this page, however we can order these in, depending on availability, "lead" times. These useful 74LSxxx building blocks of logic IC's function are on lower voltages, eg: typically from 4.5V ~ 5.6V D.C.
