M74HCT244M1R Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the M74HCT244M1R?
  The maximum operating frequency of the M74HCT244M1R is 30 MHz, but it can vary depending on the system design and capacitive load.
• How do I handle the power-up and power-down sequencing of the M74HCT244M1R?
  It is recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This ensures that the device is properly initialized and avoids any potential latch-up or damage.
• What is the recommended operating voltage range for the M74HCT244M1R?
  The recommended operating voltage range for the M74HCT244M1R is 4.5V to 5.5V, with a typical voltage of 5V. Operating outside this range may affect the device's performance and reliability.
• How do I ensure the M74HCT244M1R is properly terminated?
  The M74HCT244M1R requires proper termination to prevent signal reflections and ensure signal integrity. This can be achieved by using a termination resistor (e.g., 22 ohms) at the end of the transmission line, or by using a termination network (e.g., Thevenin termination).
• What is the maximum capacitive load that the M74HCT244M1R can drive?
  The maximum capacitive load that the M74HCT244M1R can drive is 50 pF, but it can vary depending on the system design and operating frequency. Exceeding this limit may affect the device's performance and reliability.
