SN74ACT245DWRE4 datasheet by Texas Instruments

SN74ACT245DWRE4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ACT245DWRE4?
  The maximum operating frequency of the SN74ACT245DWRE4 is 100 MHz, but it can vary depending on the system design and capacitive loading.
• How do I handle the power sequencing of the SN74ACT245DWRE4?
  It is recommended to power up the VCC pin before the input signals to prevent unwanted output states. Also, ensure that the input signals are stable before powering up the device.
• What is the recommended termination scheme for the SN74ACT245DWRE4?
  The recommended termination scheme for the SN74ACT245DWRE4 is to use a 50-ohm series resistor at the output of each driver, and a 50-ohm parallel terminator at the far end of the transmission line.
• Can I use the SN74ACT245DWRE4 in a 3.3V system?
  Yes, the SN74ACT245DWRE4 can operate in a 3.3V system, but the input voltage must not exceed 3.6V to ensure reliable operation.
• How do I handle the thermal management of the SN74ACT245DWRE4?
  The SN74ACT245DWRE4 has a maximum junction temperature of 150°C. Ensure good airflow around the device, and consider using a heat sink if the device is expected to operate at high temperatures or high frequencies.
