Each output is in the high-impedancestate when the associated output-enable (OE) input is high.Active bus-hold circuitry holds unused or undriven inputs at a valid logic state. Use of pullup or pulldown resistorswith the bus-hold circuitry is not recommended.This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs,preventing damaging current backflow through the device when it is powered down.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 INFORMATIONTASOIC − D−40°C to 85°CSOP − NSSSOP − DBTSSOP − PWPACKAGE†TubeTape and reelTape and reelTape and reelTubeTape and reelORDERABLEPART NUMBERSN74LVT125DSN74LVT125DRSN74LVT125NSRSN74LVT125DBRSN74LVT125PWSN74LVT125PWRTOP-SIDEMARKINGLVT125LVT125LX125LX125†Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelinesare available at www.ti.com/sc/package.Please 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.
