SN74F74DRG4 datasheet by Texas Instruments

SN74F74DRG4 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the SN74F74DRG4?
  The recommended operating voltage range for the SN74F74DRG4 is 4.5V to 5.5V, although it can operate as low as 3.5V with reduced performance.
• How do I handle the power-up and power-down sequences for the SN74F74DRG4?
  It is recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This helps prevent unwanted latch-up or oscillation.
• What is the maximum clock frequency that the SN74F74DRG4 can handle?
  The maximum clock frequency that the SN74F74DRG4 can handle is 100 MHz, although this may vary depending on the specific application and operating conditions.
• How do I ensure that the SN74F74DRG4 is properly terminated to prevent signal reflections?
  It is recommended to use a series terminator (e.g. 33 ohms) at the far end of the clock signal trace, and a parallel terminator (e.g. 50 ohms) at the near end of the clock signal trace.
• What is the maximum output current that the SN74F74DRG4 can sink or source?
  The maximum output current that the SN74F74DRG4 can sink or source is 24 mA, although this may vary depending on the specific application and operating conditions.
