Package

The CD4512BE is typically packaged in a dual in-line package (DIP) format, specifically a 16-pin DIP. It may also be available in surface-mount packages like SOIC or TSSOP, depending on the manufacturer.

Pinout

The CD4512BE is a dual 4-bit priority encoder. It features a total of 16 pins. The pin functions are as follows:
1. Pins 1-4 (A0-A3): Data inputs (4 bits).
2. Pins 5-6 (E1, E2): Enable inputs. E1 and E2 must be high for the encoder to function.
3. Pin 7 (G): Group select output, indicating if any input is active.
4. Pin 8 (VSS): Ground (0V) supply.
5. Pin 9 (D0): Most significant bit output.
6. Pin 10 (D1): Second most significant bit output.
7. Pin 11 (D2): Third most significant bit output.
8. Pin 12 (D3): Least significant bit output.
9. Pin 13 (VDD): Positive supply voltage.
10. Pins 14-16: Not connected or reserved for future use (depends on specific package).
The CD4512BE encodes the highest priority active input into a binary output, facilitating efficient data handling in digital circuits.
