CD4019BF3A datasheet by Texas Instruments

CD4019BF3A Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the CD4019BF3A can handle?
  The CD4019BF3A can handle clock frequencies up to 10 MHz, but it's recommended to keep it below 5 MHz for reliable operation.
• How do I ensure that the CD4019BF3A is properly powered?
  The CD4019BF3A requires a single 5V power supply, and it's essential to decouple the power pins with 0.1uF capacitors to prevent noise and oscillations.
• Can I use the CD4019BF3A as a simple inverter or buffer?
  Yes, the CD4019BF3A can be used as a simple inverter or buffer by connecting the input to the output through a resistor, but be aware that this may affect the propagation delay and rise/fall times.
• How do I handle the output enable (OE) pin?
  The OE pin is active-low, meaning that the output is enabled when OE is low (connected to GND) and disabled when OE is high (connected to VCC).
• What is the maximum output current that the CD4019BF3A can sink or source?
  The CD4019BF3A can sink or source up to 1mA of current per output pin, but it's recommended to keep the output current below 0.5mA for reliable operation.
