M74HC4020B1R datasheet by STMicroelectronics

M74HC4020B1R Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for M74HC4020B1R?
  The recommended operating voltage range for M74HC4020B1R is 2V to 6V, with a typical voltage of 5V.
• How do I handle the output enable (OE) pin in M74HC4020B1R?
  The output enable (OE) pin should be connected to GND to enable the outputs. If left floating, the outputs will be in a high-impedance state.
• What is the maximum clock frequency supported by M74HC4020B1R?
  The maximum clock frequency supported by M74HC4020B1R is 25 MHz, but it can vary depending on the operating voltage and load conditions.
• Can I use M74HC4020B1R as a level shifter?
  Yes, M74HC4020B1R 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 reliable data transfer with M74HC4020B1R?
  To ensure reliable data transfer, ensure that the clock signal is clean and has a fast rise and fall time. Also, use a pull-up resistor on the data lines to prevent data corruption.
