Pinout
The CD4512BE is a CMOS 8-channel data selector/multiplexer. It has 16 pins in total. Here is a concise overview of its pin configuration and functions:
1. VSS (Pin 8): Ground pin.
2. VDD (Pin 16): Supply voltage pin.
3. A, B, C (Pins 11, 10, 9): Select inputs used to choose which data input is connected to the output.
4. INHIBIT (Pin 15): Disables the multiplexer when high; no data is selected.
5. STROBE (Pin 7): When low, it enables the selected input to the output; when high, the output is forced low.
6. Y (Pin 6): Output pin reflecting the selected input.
7. I0 to I7 (Pins 1-5, 12-14): Data input pins (I0 through I7).
The CD4512BE routes one of the eight input data lines to a single output line based on the binary value applied to the select inputs (A, B, C). The INHIBIT and STROBE pins control the overall functionality, enabling or disabling the output as needed.
