This device performs the Boolean function Y = A.Each circuit functions as an independent inverter, but because of the Schmitt action, the inverters have differentinput threshold levels for positive-going (VT+) and negative-going (VT−) signals.ORDERING INFORMATIONTAPDIP − E−55°C to 125°CSOIC − MPACKAGE†TubeTubeTape and reelORDERABLEPART NUMBERCD74AC14ECD74AC14MCD74AC14M96TOP-SIDEMARKINGCD74AC14EAC14M†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelinesare available at www.ti.com/sc/package.FUNCTION TABLE(each inverter)INPUTAHLOUTPUTYLHlogic diagram, each inverter (positive logic)AYPlease be aware that an important notice concerning availability, standard warranty, and use in critical applications ofTexasInstruments semiconductor products and disclaimers thereto appears at the end of this data sheet.PRODUCTION DATA information is current as of publication date.Products conform to specifications per the terms of Texas Instrumentsstandard warranty.
