What it is — a dual 4-input NOR gate in the 74HC family
The 74HC4002D/C118: Dual 4-input NOR gate from the 74HC series, in a 14-SOIC package.
The 17 ns propagation delay at 6V and 50 pF load is typical for 74HC — fast enough for most control logic, clock gating, or address decoding up to a few tens of MHz, but not for high-speed memory interfaces. The 2 µA quiescent current is the standby draw; the real power is in the switching, which scales with frequency and load capacitance. The 5.2 mA output drive is enough to light a standard LED or drive a CMOS input, but don't expect to switch a relay directly — that needs a buffer or transistor.
Package and footprint — 14-SOIC, no surprises
The supplier device package is 14-SO, which is the same land pattern. No exotic pitch, no hidden thermal pad — just a straightforward SOIC that reflows cleanly with a standard profile. The bulk shipping medium means it arrives in a tube or bag, not on a reel, so plan for manual placement or a tube feeder if you're running a pick-and-place line.
Lifecycle — still active, no end-of-life worry
No last-time-buy clock ticking, no forced redesign.
