let me try to explain to our customers that the signification of 118, in the requested part number 1727-2062-2-ND / 74HCT4538D,118 is really not listed in the Data Sheet but the meaning is:
11 for their latest internal package version: SOT109-1
8 for the full Standard Packaging: 2500 per Tape & Reel
P.S.: Nexperia was carved out from NXP Semiconductors and the original specification
goes even further back to Philips Semiconductors and is fully backward compatible.
