CERDIP packaged military – or industrial-grade CMOS integrated circuit (IC) it’s an early ceramic dual-in-line (CDIP) 4000-series logic chip
Historical Context
The ceramic “BCL” variants were military-grade or higher spec. components designed for rugged environments, featuring hermetic ceramic packages with gold-plated or tin leads rather than standard commercial plastic molding.
- Ceramic Package: Usually designated with an L suffix (MC14070BCL) in Motorola’s catalog, this CERDIP package provides a hermetic seal.
Key Differences from Modern Plastic 4070 Chips
| Feature | Motorola MC14070BC (Ceramic, 1982) | Standard Modern 4070 (Plastic) |
|---|---|---|
| Material | Hermetic Ceramic (CERDIP); highly resistant to moisture and chemical corrosion. | Molded Epoxy Plastic; prone to moisture absorption over decades. |
| Thermal Dissipation | Higher power derating capabilities at elevated temperatures. | Standard thermal dissipation profile. |
| Buffering | Fully Buffered (B-Series). | Fully Buffered (B-Series). |
| Performance | 1982 manufacturing tolerances; may exhibit slightly higher propagation delays (~350ns) than contemporary modern reproductions. | Faster internal gate switching due to modern silicon wafer processing. |

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.
