74FCT244CTQG Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the 74FCT244CTQG is 4.5V to 5.5V, with a typical voltage of 5V.
  • When the input pins are not in use, they should be tied to VCC or GND through a pull-up or pull-down resistor to prevent floating inputs and reduce power consumption.
  • The maximum frequency of operation for the 74FCT244CTQG is 100 MHz, but this can vary depending on the specific application and operating conditions.
  • To ensure signal integrity, use controlled impedance PCB traces, terminate the outputs with a suitable load, and consider using series termination resistors to reduce reflections and ringing.
  • The 74FCT244CTQG is a Fast CMOS (FCT) device, which is compatible with other 5V CMOS logic families, but may not be directly compatible with other logic families such as TTL or ECL.
