Instructions for Use:

1. Power Supply:

   • Connect the Vcc pin to a 5V supply.
   • Connect the GND pin to ground.

2. Presetting the Counter:

   • Set the initial count by applying logic levels to the preset inputs (A, B, C, D).
   • The counter will load the preset value on the rising edge of the clock signal when the MR (Master Reset) pin is high.

3. Clocking the Counter:

   • Apply a clock signal to the CP (Clock Pulse) pin.
   • The counter will increment on each rising edge of the clock signal.

4. Resetting the Counter:

   • To reset the counter, apply a low signal to the MR (Master Reset) pin.
   • The counter will be reset to 0000 (all outputs low).

5. Reading the Output:

   • The current count can be read from the complementary outputs (QA, QB, QC, QD, /QA, /QB, /QC, /QD).

6. Handling and Storage:

   • Handle the device with care to avoid static damage.
   • Store in a dry, cool place away from direct sunlight.

For detailed specifications and further information, refer to the datasheet provided by the manufacturer.
