CD4071 IC is a quad 2-input OR gate. It is a part of the CD4000 IC series. CD4071 is based on the complementary MOS (CMOS) technology, integrated with N- and P-channel enhancement mode transistors. The IC has an equal source and sink current capabilities and conforms to the standard B series output drive. All inputs to the IC are static protected through clamping diodes. The IC also offers features such as high noise immunity, low thermal dissipation. The output of the IC always comes in TTL, which makes it easy to use with CMOS, NMOS, and other TTL devices.
What is an OR Gate?
The OR gate is a digital logic gate that is generally used in digital logic design. The output of an OR gate is high or 1, if even a single input to the gate is at a logical high. on the other hand, An OR gate will yield a logical Low if anyone of its input go LOW.
CD4071 Key Features
- Low power TTL compatibility:
- Fan out of 2 driving 74L or 1 driving 74LS
- 5V–10V–15V parametric ratings
- Symmetrical output characteristics
- Maximum input leakage 1 µA at 15V over full temperature range
