The MC54HC02J is a quad 2-input NOR gate from the HC (High-speed CMOS) family, manufactured by Freescale Semiconductor, now NXP Semiconductors. This integrated circuit contains four independent NOR gates, each with two inputs and one output. A NOR gate performs the inverse of the OR operation: the output is HIGH (1) only if both inputs are LOW (0); otherwise, the output is LOW (0). The 54 prefix indicates that this part is specified for operation over the military temperature range. The HC family offers high speed and low power consumption compared to older logic families.
