Active 4-bit OTPROM MCU — what the lifecycle means for your BOM
The HD4074618FS: For production runs where the firmware is final and the volume justifies the mask cost, the 4-bit core keeps the BOM lean on low-complexity control tasks.
Bulk packaging and procurement posture
The HD4074618FS ships in Bulk — loose units in anti-static tubes or trays, not tape-and-reel. This matters if your pick-and-place line expects reeled components; bulk parts may need tube feeders or hand-loading for small-batch assembly. Sourced to order against your BOM quantity through independent distribution. The Active status means the manufacturer still supports the part, so lead time is typically within the standard semiconductor window for this node.
