CD4520BNSR datasheet by Texas Instruments

CD4520BNSR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for CD4520BNSR?
  The recommended operating voltage range for CD4520BNSR is 4.5V to 20V, although it can operate up to 22V 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 CD4520BNSR?
  The maximum clock frequency for CD4520BNSR is 25 MHz, but it can be affected by the operating voltage, temperature, and load capacitance.
• Can I use CD4520BNSR as a level shifter?
  Yes, CD4520BNSR can be used as a level shifter, but it's not recommended as it's not designed for that purpose. Instead, use a dedicated level shifter IC for reliable operation.
• How do I ensure proper power sequencing when using CD4520BNSR?
  To ensure proper power sequencing, apply power to the VCC pin before applying any input signals, and ensure that the input signals are stable before enabling the outputs.
