Device identity and production status
The 54H74DM: Texas Instruments lists this part as Active in production, so it remains a current catalog item for new builds and legacy BOM support.
Package and compliance note
The 54H74DM ships in Bulk packaging, which is the standard tube or tray format for through-hole logic ICs — no reel or tape handling required for prototype or low-volume assembly. This part is marked RoHS non-compliant, meaning it contains lead in the solder finish or die-attach. For designs requiring RoHS exemption or lead-free assembly, a functional equivalent from the 74AS or 74HC family may be needed.
