When the strobe is high, all outputs are low. Whenthe strobe is low, a 4-bit word is selected from one of two sources and is routed to the four outputs. The devicesprovide true data.ORDERING INFORMATIONTAPACKAGE†QFN – RGYPDIP – NSOIC–DSOIC – D–40°C to 85°CSOP – NSSSOP – DBTSSOPPWTSSOP – PWTVSOP – DGVCDIP – J–55°C to 125°CCFP – WLCCC – FKTape and reelTubeTubeTape and reelTape and reelTape and reelTubeTape and reelTape and reelTubeTubeTubeORDERABLEPART NUMBERSN74AHC157RGYRSN74AHC157NSN74AHC157DSN74AHC157DRSN74AHC157NSRSN74AHC157DBRSN74AHC157PWSN74AHC157PWRSN74AHC157DGVRSNJ54AHC157JSNJ54AHC157WSNJ54AHC157FKTOP-SIDEMARKINGHA157SN74AHC157NAHC157AHC157HA157HA157HA157SNJ54AHC157JSNJ54AHC157WSNJ54AHC157FK†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.
