Description

The 4075 Triple 3-Input OR Gate is a CMOS logic IC designed for digital logic applications requiring multiple OR operations. This IC contains three independent OR gates, each with three inputs, allowing for complex logic combinations in a single package. Housed in a 14-pin Dual Inline Package (DIP), the 4075 is ideal for digital electronics projects, signal processing, decision-making circuits, and educational applications.

CMOS technology ensures low power consumption, high noise immunity, and wide operating voltage range, making the 4075 suitable for battery-operated and high-performance digital systems. Each gate performs the OR function: the output is HIGH if any one or more inputs are HIGH, and LOW only when all inputs are LOW.
