Part Number: SN74HC14

From the detail data sheet, it show SN74HC14DR with "NIPDAU | SN" at the "Lead finish/ Ball material" column but SN74HC14DRG4  with "NIPDAU " at "Lead finish/ Ball material". Are both the same part?

    Footnote (6) says:

    Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line.

    The SN74HC14DR is made at multiple manufacturing sites, which use different lead finishes. Both tin and nickel/palladium/gold conform to the datasheet specifications.
