The IC 7432 integrates four independent 2-input OR gates into a single 14-pin Dual In-line Package (DIP). Each gate outputs a logic HIGH if at least one input is HIGH. It operates on a standard 5V TTL power supply and supports full compatibility with other devices in the 7400-series TTL family.
Engineers use the 7432 to implement simple logic operations in control logic, digital circuits, and signal routing systems. It provides fast switching, stable voltage thresholds, and low power dissipation, making it suitable for both high-performance systems and educational setups.
The IC performs well in decision-making circuits, alarm systems, signal merging, and logic enabling functions. Because of its versatility and simplicity, the 7432 is often chosen for both prototyping and production environments. It offers clean logic operation and consistent output behavior across standard operating conditions.
