Hello,
We have listed here on our Digikey site, along with other Disti's have this part SN74LVC1G3157YZTR, as well as an orderable part number. but no clarity of what the ZTR "T" stands for in the part number. Are you able to help me with finding this info? https://www.digikey.com/en/products/detail/texas-instruments/SN74LVC1G3157YZTR/2696391
Thank you,
