CD4521BNSR datasheet by Texas Instruments

CD4521BNSR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD4521BNSR?
  The recommended operating voltage range for CD4521BNSR 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 CD4521BNSR?
  The maximum clock frequency for CD4521BNSR is 10 MHz, but it can be operated at higher frequencies with reduced performance and increased power consumption.
• How do I ensure proper power sequencing for CD4521BNSR?
  To ensure proper power sequencing, apply power to VCC before applying clock or input signals. Also, ensure that the power supply is stable and within the recommended operating range before applying clock or input signals.
• What is the purpose of the VCC pin on CD4521BNSR?
  The VCC pin is the power supply pin, which should be connected to a stable power source within the recommended operating range (4.5V to 5.5V).
