Quad NOR gate with 8.5 ns propagation delay at 5 V
The SN74AHC02DR: The 8.5 ns maximum propagation delay at 5 V with a 50 pF load defines the speed ceiling for this gate in a standard CMOS fan-out configuration. Symmetric 8 mA output drive (both high and low) means it can directly drive downstream logic inputs or small loads without additional buffering, provided the total capacitive load stays within the datasheet derating curve.
Active lifecycle with ROHS3 compliance
The 2 µA maximum quiescent current keeps the power budget low in battery-powered or always-on subsystems. When the gate inputs are held at valid logic levels, the standby draw is negligible, which matters for systems that spend most of their time in a low-power idle state.
Standard SOIC footprint for PCB integration
No exposed thermal pad or special PCB land pattern is required — standard SOIC-14 footprint with a 0.050" (1.27 mm) pitch will match. The surface-mount assembly is compatible with reflow soldering profiles typical for lead-free boards.
