MC74HC00N – NATIONAL SEMICONDUCTOR

The MC74HC00N is a high-speed silicon-gate CMOS quad 2-input NAND gate fabricated by National Semiconductor. This device operates within a supply voltage range of 2.0V to 6.0V, exhibiting a typical propagation delay of 7ns at 5V and a 15pF load. The ‘HC00’ designation indicates compatibility with standard TTL logic voltage levels, allowing for direct interfacing with TTL components. The N suffix denotes a 14-pin plastic dual in-line package (PDIP). Internal ESD protection circuitry is incorporated, providing a minimum human body model (HBM) withstand voltage of 2kV. The Fairchild date code of 2001 and the National Semiconductor date code of 1997 suggest this part may have been manufactured under license or represents inventory from before Fairchild’s acquisition of National Semiconductor. The device features a quiescent current (Icc) of typically 2µA at 25°C, minimizing power consumption in static conditions.
