Description
4075 IC Triple 3-Input
OR Gate
DIP-14
The 4075 IC Triple 3-Input OR Gate DIP-14 is a CMOS logic device containing three independent 3-input OR gates. Each gate performs the logical OR function, outputting HIGH when any one or more of its inputs are HIGH. Designed using advanced CMOS technology, the IC ensures low power consumption and high noise immunity. It operates over a wide voltage range, making it compatible with both TTL and CMOS logic systems. The 4075 IC is housed in a standard 14-pin dual in-line package (DIP), making it easy to use on breadboards and through-hole PCBs for digital logic design, signal processing, and control circuits.
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.
Check the truth table below to see the result for any combination of inputs.
