CD4532 8-Bit Priority Encoder DIP-16 (CD4532 DIP IC)
The CD4532 is a high-voltage CMOS integrated circuit that functions as an 8-bit priority encoder. It accepts eight active-high data inputs and provides a 3-bit binary weighted code representing the highest-order input that is active. This ensures that if multiple inputs are triggered simultaneously, only the one with the highest priority is encoded.
This IC is primarily used in interrupt controllers, A/D converters, and keyboard encoders. It is a common component for Arduino electronics projects in India where multiple sensors or switches need to be monitored using a limited number of microcontroller pins by identifying the most critical active signal.
