M74HCT244B1R Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the M74HCT244B1R?
  The maximum operating frequency of the M74HCT244B1R is 50 MHz, but it can vary depending on the capacitive load and the output current.
• How do I handle the power-up and power-down sequencing of the M74HCT244B1R?
  It is recommended to power up the VCC pin before the input signals and power down the VCC pin after the input signals to prevent unwanted output states.
• What is the recommended operating voltage range for the M74HCT244B1R?
  The recommended operating voltage range for the M74HCT244B1R is 4.5V to 5.5V, but it can operate from 4.0V to 5.5V with reduced performance.
• How do I ensure the M74HCT244B1R is not damaged by electrostatic discharge (ESD)?
  Handle the device by the body, use an anti-static wrist strap, and store the device in an anti-static bag or container to prevent ESD damage.
• What is the maximum output current that the M74HCT244B1R can sink or source?
  The maximum output current that the M74HCT244B1R can sink or source is 6mA per output pin, but it can be limited by the total device power dissipation.
