CD4511BPWG4 datasheet by Texas Instruments

CD4511BPWG4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the CD4511BPWG4?
  The recommended operating voltage range for the CD4511BPWG4 is 4.5V to 5.5V, although it can operate from 3V to 18V with reduced performance.
• How do I handle the output enable (OE) pin?
  The output enable (OE) pin is active-low, meaning it should be connected to GND to enable the outputs. Leaving it unconnected or connecting it to VCC will disable the outputs.
• What is the maximum clock frequency for the CD4511BPWG4?
  The maximum clock frequency for the CD4511BPWG4 is 10 MHz, although it can operate at higher frequencies with reduced performance and increased power consumption.
• How do I ensure proper data retention during power-down?
  To ensure proper data retention during power-down, the VCC pin should be ramped down slowly (less than 1 ms) to prevent data loss. A capacitor (e.g., 0.1 μF) between VCC and GND can help filter out noise and ensure a clean power-down.
• What is the purpose of the VSS pin?
  The VSS pin is the ground pin and should be connected to the system ground (GND) to provide a return path for the chip's internal circuitry.
