Description
The 74HC02, 74HCT02 is a quad 2-input NOR gate. Inputs include clamp diodes. This enables the use of current limiting resistors to interface inputs to voltages in excess of VCC.
A quad 2-input NOR gate is a digital logic gate that contains four individual NOR gates, with each gate having two input signals and one output signal. The output of each NOR gate is the logical NOR operation of its two input signals.
General Specifications:
1. The gate consists of four individual 2-input NOR gates.
2. Each 2-input NOR gate has two input signals, labeled A and B, and one output signal, labeled Y.
3. For each 2-input NOR gate, the inputs A and B are connected to the corresponding input pins.
4. The output of each NOR gate is the logical NOR operation of its two input signals (Y = A NOR B).
5. The output pins of the four NOR gates are labeled Y1, Y2, Y3, and Y4, respectively, representing the outputs of the quad 2-input NOR gate.
