SN74ACT245DWRG4 datasheet by Texas Instruments

SN74ACT245DWRG4 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ACT245DWRG4?
  The maximum operating frequency of the SN74ACT245DWRG4 is 100 MHz.
• Can I use the SN74ACT245DWRG4 in a 3.3V system?
  Yes, the SN74ACT245DWRG4 is compatible with 3.3V systems, but it can also operate at 5V. However, the output voltage will be limited to the VCC supply voltage.
• How do I handle the heat dissipation of the SN74ACT245DWRG4?
  The SN74ACT245DWRG4 has a thermal pad on the bottom of the package, which should be connected to a thermal ground plane on the PCB to dissipate heat. Additionally, 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.
• Can I use the SN74ACT245DWRG4 as a level translator between 1.8V and 3.3V?
  Yes, the SN74ACT245DWRG4 can be used as a level translator between 1.8V and 3.3V. However, ensure that the input voltage is within the recommended operating range of the device, and that the output voltage is within the recommended operating range of the receiving device.
• What is the propagation delay of the SN74ACT245DWRG4?
  The propagation delay of the SN74ACT245DWRG4 is typically around 2.5 ns, but this can vary depending on the operating frequency, temperature, and output load.
