These are genuine vintage RCA parts (see photographs for RCA logo) date code 224R2
How to Decode “224R2”
- Year Code (
2): Represents the last digit of the calendar year. For early ceramic CMOS technology (such as the RCA CD4000), this points to either 1972 or 1982. You can usually narrow down the decade by looking at the part number prefix or the overall design era of the surrounding equipment.
- Week Code (
24): Indicates the 24th week of that year, which corresponds to mid-June.
- Suffix Code (
R2): Stands for Revision 2. This denotes the second major revision or stepping level of the internal silicon die mask, layout modifications, or a specific wafer fabrication plant tracking code.
1972: CERDIP (Ceramic Dual In-line Package) technology was heavily utilized by RCA during this time for high-reliability, military-grade, or early CMOS (CD4000 series) and linear ICs. If the font looks slightly more angular, or if it is a very early logic chip, it is likely from 1972.
PLEASE NOTE!
These parts came to us as part of a lot of surplus stock from a large ‘milspec’ type Co. and have been kept in storage for some time, we have therefore classified them as ‘new other’, they are however pristine, and, as with all our products they come with a full guarantee.
If you have similar items to this, or indeed any electronic components that are surplus to requirements please contact us with details.
