The output is disabled when theoutput-enable (OE) input is high. When OE is low, true data is passed from the A input to the Y output.To ensure the high-impedance state during power up or power down, OE should be tied to VCC through a pullupresistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.ORDERING INFORMATIONTAPACKAGE†SOT (SOT-23) − DBV−40°C to 85°CSOT (SC-70) − DCKSOT (SOT-553) − DRLReel of 3000Reel of 250Reel of 3000Reel of 250Reel of 4000ORDERABLEPART NUMBERSN74AHC1G125DBVRSN74AHC1G125DBVTSN74AHC1G125DCKRSN74AHC1G125DCKTSN74AHC1G125DRLRTOP-SIDEMARKING‡A25_AM_AM_†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines areavailable at www.ti.com/sc/package.‡The actual top-side marking has one additional character that designates the assembly/test site.FUNCTION TABLEINPUTSOELLHAHLXOUTPUTYHLZlogic diagram (positive logic)OEA124YPlease 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.
