SN74HCT244DWRG4 datasheet by Texas Instruments

SN74HCT244DWRG4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74HCT244DWRG4?
  The maximum operating frequency of the SN74HCT244DWRG4 is 50 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 SN74HCT244DWRG4?
  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 termination scheme for the SN74HCT244DWRG4?
  The recommended termination scheme is to use a 1-kΩ to 10-kΩ pull-up resistor to VCC or a 1-kΩ to 10-kΩ pull-down resistor to GND, depending on the system requirements.
• Can I use the SN74HCT244DWRG4 in a 5V system?
  Yes, the SN74HCT244DWRG4 is compatible with 5V systems, but it is recommended to use a voltage regulator to ensure a stable 4.5V to 5.5V supply voltage.
• How do I handle the thermal management of the SN74HCT244DWRG4?
  The SN74HCT244DWRG4 has a maximum junction temperature of 150°C. It is recommended to use a heat sink or thermal pad to dissipate heat, especially in high-power or high-frequency applications.
