SN74BCT245DW Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the SN74BCT245DW is 100 MHz, but it can vary depending on the capacitive load and the output current.
  • It is recommended to tie the OE pin to a valid logic level (either VCC or GND) during power-up and power-down to prevent unwanted output transitions.
  • The recommended termination scheme is to use a series resistor (Rs) and a parallel capacitor (Cp) at the output of each buffer, with Rs = 22-33 ohms and Cp = 10-22 pF.
  • Yes, the SN74BCT245DW can be used as a level translator between 3.3V and 5V logic, but ensure that the input voltage is within the recommended operating range and that the output voltage is within the specified output voltage range.
  • The input voltage range for the SN74BCT245DW is 2.3V to 5.5V, but it is recommended to keep the input voltage within the recommended operating range of 2.7V to 5.5V for reliable operation.
