Instructions for Use

1. Power Supply:

   • Connect Vcc (pin 16) to the positive supply voltage (2.0 V to 5.5 V).
   • Connect GND (pin 8) to the ground.

2. Clock Input:

   • Apply the clock signal to the CP (pin 10) to advance the counter.
   • The counter advances on the rising edge of the clock signal.

3. Reset:

   • Connect MR (pin 1) to Vcc or GND to control the reset function.
   • When MR is high (Vcc), the counter is reset to 0000.
   • When MR is low (GND), the counter operates normally.

4. Outputs:

   • The outputs QA (pin 3), QB (pin 2), QC (pin 4), and QD (pin 5) provide the binary count from 0000 to 1111 (0 to 15 in decimal).

5. Cascade Operation:

   • To cascade multiple counters, connect the ripple carry output (RCO, pin 11) to the clock input (CP) of the next counter.

6. Decoding Outputs:

   • Use the outputs directly or through additional logic to decode specific count values.

7. Handling Precautions:

   • Ensure proper handling to avoid static damage.
   • Do not exceed the maximum ratings specified in the datasheet.

8. Testing:

   • Verify the functionality by applying a known clock signal and monitoring the output states with a logic analyzer or oscilloscope.
