www.ti.com SNOS082C –JULY 1998–REVISED APRIL 2013 54AC14HexInverterwithSchmittTriggerInput Check forSamples: 54AC14 1FEATURES DESCRIPTION The 'AC14 containssixinvertergates each witha 23• ICC Reduced by 50% Schmitttriggerinput.The 'AC14 containssixlogic• Outputs Source/Sink24 mA inverterswhich acceptstandardCMOS inputsignals
- Standard MilitaryDrawing (SMD) and providestandardCMOS outputlevels.They are capableoftransformingslowlychanginginputsignals– 54AC14: 5962-87624 into sharplydefined,jitter-freeoutput signals.In• 54AC14 now Qualifiedto300Krad RHA addition,they have a greaternoise margin thanDesignation,RefertotheSMD forMore conventionalinverters.Information The 'AC14 has hysteresisbetween thepositive-going and negative-goinginputthresholds(typically1.0V) whichisdeterminedinternallyby transistorratiosand isessentiallyinsensitiveto temperatureand supply voltagevariations.
