CD4075 IC Three OR Gates 3-input

Description

CD4075 – An IC with Three OR Gates (3-input) The CD4075 is a CMOS chip with three 3-input OR gates. Because each gate has three inputs and it has three gates inside, it’s usually called a Triple 3-Input OR Gate. An OR gate is a logic gate that outputs HIGH if either of its inputs is HIGH. Each of the OR-gates in this chip has 3 inputs.

A 3-input OR gate works just like a normal OR gate. Its output becomes HIGH if any of the inputs are HIGH. Otherwise, its output is LOW.

First of all, you need a power supply voltage of 3 to 15V. Some versions of the chip support up to 20V. Check the datasheet of your version of the chip for exact values. To be able to use any of the OR gates in the chip, you need to first connect the VDD pin to the positive supply terminal and the GND pin to the negative supply terminal. The A, B, and C pins are the inputs to th
