binary encoder for keypad systems

The CD4532 DIP 8-Input Priority Encoder is a CMOS IC that converts up to 8 input signals into a 3-bit binary output, prioritizing the highest-order active input. With an enable input (EN) to control the encoding process and a wide voltage range (3V to 18V) for compatibility with both low-voltage and standard logic systems, the CD4532 is ideal for digital encoding, priority selection, and control systems. It comes in a DIP-16 package, making it easy to integrate into breadboards, PCBs, and prototype designs.
