Instructions for Using CD4002AE:
Supply Voltage:
- Ensure the supply voltage is within the range of 3.0 V to 18.0 V.
- Avoid exceeding the maximum supply voltage to prevent damage to the device.
Input Voltage Levels:
- For a high input level, ensure the voltage is at least 70% of VDD.
- For a low input level, ensure the voltage is no more than 30% of VDD.
Output Voltage Levels:
- When sourcing current (output high), the output voltage should be at least 90% of VDD.
- When sinking current (output low), the output voltage should not exceed 1.0 V.
Current Ratings:
- The input current should not exceed 1.0 μA for a low input and should not be less than -1.0 μA for a high input.
- The output current should not exceed 1.0 mA when sinking and should not be less than -1.0 mA when sourcing.
Propagation Delay:
- The propagation delay time is typically 35 ns at a supply voltage of 5 V and a frequency of 1 MHz.
Power Dissipation:
- The maximum power dissipation is 500 mW. Ensure adequate heat dissipation if operating near this limit.
Handling Precautions:
- Handle the device with care to avoid static discharge which can damage the sensitive components.
- Use appropriate ESD protection measures during handling and installation.
Storage:
- Store the device in a dry, cool place to prevent moisture damage.
Soldering:
- Follow recommended soldering profiles to avoid thermal damage to the device.
Testing:
- Use a multimeter or an oscilloscope to verify the correct operation of the device after installation.
