Présentation
Description
Key features include:
- Four input lines, A, B, C, and D, which are used to select one of the 16 outputs.
- A latch enable (LE) input that allows the inputs to be stored, providing stable outputs even if the input data changes.
- An active-low enable input (E) that must be low for the device to be operational.
- A clear (CLR) input that resets all outputs to low when activated.
The outputs are high when selected and low otherwise, making the 74HC4514D suitable for a variety of applications, such as data routing, memory addressing, and instrumentation. It is packaged in a standard DIP, SOIC, or SSOP format, facilitating easy integration into electronic circuits.

Pinout
Key functions:
- Inputs: A0-A3 (address inputs), LE (latch enable), E̅ (enable).
- Outputs: Q0-Q15 (decoded outputs).
- When LE is HIGH, the address inputs are latched, and the output reflects the address inputs.
- When E̅ is LOW, the decoder is enabled, otherwise, all outputs are LOW.
- Q0-Q15 correspond to the binary value input to A0-A3 when the device is enabled.
This device is typically used for applications needing multiple outputs controlled by fewer inputs, such as memory addressing and selecting among multiple data lines.
