Functional Features

The CD74HC4515EN offers the following functional features:

• Decade counter mode: The IC can count from 0 to 9 and reset back to 0.
• Binary-to-decimal decoder mode: It converts a 4-bit binary input into its corresponding decimal output.
• Lamp Test (LT) and Blanking Input (BI): These features allow for testing and blanking of the outputs.
• Count Up/Down: The IC can count up or down based on the state of the C/D pin.
• Master Reset (MR): This pin resets the counter to 0 when activated.
• Enable Parallel Inputs (ENP): Allows parallel loading of data into the counter.
• Enable Count Up (ENT): Enables counting up when activated.
• Clock Input (CLK): The clock signal determines the speed at which the counter advances.

Advantages and Disadvantages
