Instructions for Using CD4518BE

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the operating range of 3.0V to 18V.
   • Connect the ground (GND) pin to a stable reference point.

2. Input Signals:

   • Apply high-level input voltages (V_IH) between V_CC - 1.5V and V_CC.
   • Apply low-level input voltages (V_IL) between 0V and 1.5V.

3. Output Signals:

   • The output voltage (V_OH) when high should be between V_CC - 0.5V and V_CC - 0.1V at a load current of 0.4 mA.
   • The output voltage (V_OL) when low should be between 0V and 0.5V at a load current of 16 mA.

4. Propagation Delay:

   • The propagation delay time (t_pLH, t_pHL) is typically 150 ns at V_CC = 5V and f = 1 MHz.

5. Temperature Considerations:

   • Operate the device within the temperature range of -40掳C to 85掳C.
   • Store the device within the temperature range of -65掳C to 150掳C.

6. Handling:

   • Handle the device with care to avoid static discharge, which can damage the internal circuits.
   • Use appropriate ESD protection measures during handling and installation.

7. Application:

   • The CD4518BE is a dual 4-bit binary counter. Each counter has separate clock, reset, and enable inputs.
   • Connect the clock input to the desired clock signal.
   • Use the reset input to reset the counter to zero.
   • Use the enable input to control whether the counter is active or not.

8. Pin Configuration:

   • Refer to the datasheet for the specific pin configuration and connections.

By following these guidelines, you can ensure reliable operation of the CD4518BE in your circuit.
