Quad 2-input NOR gate for wide-voltage digital logic
The CD74AC02M96 is a quad 2-input NOR gate from the 74AC family, packaged in a 14-SOIC (0.154", 3.90mm width) surface-mount package. It integrates four independent NOR gates, each with two inputs, on a single IC. The 1.5V to 5.5V supply range means this gate can interface directly with both 3.3V and 5V logic families without a level translator, simplifying mixed-voltage board designs. With a military-grade operating temperature range of -55°C to 125°C, this part is suited for avionics, satellite, downhole drilling, and other high-reliability environments where commercial or industrial temperature grades would not survive.
Propagation delay and output drive for timing-critical paths
Maximum propagation delay is 11.5ns at 5V with a 50pF load — this sets the data-rate ceiling for the logic path. In a 5V system, the gate can cleanly pass a 40 MHz clock without violating setup/hold margins at the next flip-flop. Symmetrical 24mA source and sink output current means the gate drives standard CMOS and TTL loads equally well. The 24mA figure is the current available at the output pin, not the per-channel limit; derating for ambient temperature and package thermal resistance applies. Quiescent current is just 4 µA maximum — negligible in battery-powered designs, though the dynamic current scales with switching frequency and load capacitance per the standard CMOS power formula.
Package and board-fit note
The 14-SOIC (0.154", 3.90mm width) body is the narrow SOIC variant, not the wide 7.5mm body. The 1.27mm pin pitch is standard for SOIC-14, and the footprint matches industry-standard SOIC-14 land patterns. The supplier device package is listed as 14-SOIC. Available in Tape & Reel (TR) and Cut Tape (CT) options — the TR suffix on the order code indicates reel packaging for automated pick-and-place assembly. The CT option suits prototype or low-volume builds where a full reel is not needed.
Lifecycle and compliance status
As an active part in the 74AC series, it is suitable for both new designs and ongoing production. Sourced through authorized distribution channels; availability and current pricing confirmed at RFQ.
