IC CD4001

SKU: 000993 Category: Tags: , , ,


The “CD4001” is a part number associated with a specific integrated circuit (IC) from the CD4000 series, which is a family of complementary metal-oxide-semiconductor (CMOS) digital logic ICs. In particular, the CD4001 is a quad 2-input NOR gate IC. Let’s break down what this means:

1. **Quad:** The term “quad” indicates that the IC contains four identical logic gates. In the case of CD4001, each of these gates is a 2-input NOR gate.

2. **2-Input NOR Gate:** A NOR gate is a digital logic gate that performs a logical NOR operation. It has two inputs (hence “2-input”) and produces an output that is true (logic level “1”) when neither of the inputs is true. In other words, the output is “1” if both inputs are “0.” If either or both inputs are “1,” the output is “0.”

3. **CMOS:** The CD4000 series, including the CD4001, is based on complementary metal-oxide-semiconductor (CMOS) technology. CMOS ICs are known for their low power consumption, wide operating voltage range, and high noise immunity.

Here’s a bit more detail about the CD4001 IC:

– **Pin Configuration:** The CD4001 typically comes in a 14-pin dual in-line package (DIP) and follows a standard pinout configuration for CMOS logic ICs. It has four independent NOR gates, each with two input pins and one output pin.

– **Voltage Compatibility:** CMOS ICs in the CD4000 series often have a wide voltage supply range. The CD4001, for example, can typically operate from 3 to 18 volts, making it compatible with a variety of supply voltages.

– **Applications:** NOR gates are commonly used in digital logic circuits for functions like control and signal inversion. The CD4001 can be employed in various digital applications where NOR gates are required.

– **Truth Table:** The truth table for a 2-input NOR gate is as follows:
| A | B | Output |
| 0 | 0 | 1 |
| 0 | 1 | 0 |
| 1 | 0 | 0 |
| 1 | 1 | 0 |

When using the CD4001 IC in a circuit, it’s essential to refer to the manufacturer’s datasheet for detailed information on pin functions, electrical characteristics, and recommended operating conditions. This datasheet provides valuable information for designing and understanding circuits that incorporate the CD4001 IC.
