4000 – dual 3-input NOR gate plus inverter, CMOS, DIP-14 (generic)

The 4000 is the first type in the CMOS 4000 family: two independent NOR gates with three inputs each, plus a single inverter in the same package. It exists in A and UB (unbuffered) versions; the photographed chip is an A type. Like most 4000-series parts it works over a wide supply range; check the limits in the datasheet for the specific manufacturer and series. It comes in a 14-pin plastic DIP.

Condition: mixed surplus lot, untested. The bag may contain used (pulled) ICs of the same type from different manufacturers, so marking and date code vary. The photo shows one chip from this lot (SGS HBF4000AE); only the background was cleaned to white, preserving the marking and leads.

Minimum order: 1 pc.
