Device identity and logic family
The Texas Instruments 4085BDC is a CMOS AND-OR-INVERT gate, a combinatorial logic device that performs the AND-OR-INVERT function in a single package.
Package and compliance
Supplied in Bulk packaging, typical for through-hole or DIP-style CMOS logic devices that are handled individually rather than on tape-and-reel. The part is RoHS non-compliant, meaning it may contain lead or other restricted substances — this is a flag for designs requiring RoHS conformance and for end-of-life disposal documentation.
