I've been comparing the NXP datasheets for the 74LVC1G53 and 74LVC2G53 for fifteen minutes and can't spot any difference.=20 What am I not seeing? Even the marking code is the same, so spill them both and there's no way to tell the difference. Looking at the TSSOP-8 package but they both come in the same range of packages.
