CD4512BEE4 datasheet by Texas Instruments

CD4512BEE4 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the CD4512BEE4?
  The maximum clock frequency for the CD4512BEE4 is 10 MHz, but it can operate at frequencies up to 20 MHz with reduced voltage supply (VDD) and proper PCB design.
• How do I ensure proper power sequencing for the CD4512BEE4?
  To ensure proper power sequencing, apply VDD before applying any input signals, and ensure that VDD reaches its minimum specified voltage before applying clock signals.
• What is the recommended operating voltage range for the CD4512BEE4?
  The recommended operating voltage range for the CD4512BEE4 is 4.5V to 5.5V, but it can operate from 3V to 18V with reduced performance and increased power consumption.
• How do I handle unused inputs on the CD4512BEE4?
  Unused inputs should be tied to VDD or GND through a 1kΩ resistor to prevent floating inputs and reduce power consumption.
• What is the maximum output current for the CD4512BEE4?
  The maximum output current for the CD4512BEE4 is 1.5 mA per output pin, but it's recommended to limit the output current to 1 mA to ensure reliable operation.
