Topmark decodes as (per 2000 Philips Quality Manual, repeated at https://www.dutchaudioclassics.nl/TDA1541-Product-manufacturing-codes-and-markings/):

  • Commercial part number: SA572N (SA572, 16-pin dual in-line package)
  • Diffusion lot GGW17, assembly sequence 91
  • Date of manufacture 1998, week 14. Diffused at Philips Semiconductors Nijmegen (H), assembled in Bangkok (n)

Later parts carry the more recent (~2000) Philips line-3 topmark format of YYWWDAR – Year, Week, Diffusion, Assembly, (centre of) Responsibility. These later parts usually indicate “centre of responsibility” being Sunnyvale, i.e. Signetics. This matches up with the Philips datasheet indicating that this is a Signetics part.
