LM / CD 74LS16240 series FAST TTL IC's: 74LS16240 up to 74LS62260


     Back to the data sheets page

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.
