Package

The 74HC4514D is typically packaged in a 16-pin dual in-line package (DIP) or a surface mount package (SOIC). The "D" in its part number indicates a plastic DIP package.

Pinout

The 74HC4514D is a 4-to-16 line decoder/demultiplexer. It has a total of 20 pins. The pin configuration is as follows:
1. Input Pins (A0–A3): Four address inputs (pins 1, 2, 3, and 4) used to select one of the 16 output lines.
2. Enable Pins (E1, E2): Two enable inputs (pins 5 and 6) that must be activated for the decoder to function.
3. Output Pins (Y0–Y15): Sixteen outputs (pins 7 to 20) corresponding to the binary value of the input pins. Only one output is activated (low) based on the input values.
4. Ground (GND): Pin 11 connects to the ground.
5. Vcc: Pin 16 connects to the positive supply voltage.
The device is used in applications requiring address decoding and data routing, offering low propagation delay and high-speed operation.
