74HC597D,652 datasheet by NXP Semiconductors

74HC597D,652 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that can be used with the 74HC597D,652?
  The maximum clock frequency for the 74HC597D,652 is 25 MHz, but it can be limited by the system's noise margin and the quality of the clock signal.
• How do I ensure reliable data transfer with the 74HC597D,652?
  To ensure reliable data transfer, make sure to use a clock signal with a rise and fall time of less than 10 ns, and keep the data lines as short as possible to minimize signal degradation.
• Can I use the 74HC597D,652 with a 3.3V power supply?
  Yes, the 74HC597D,652 can operate with a power supply voltage as low as 2V, but the output voltage levels may not be compatible with 3.3V logic. Check the output voltage levels and adjust the power supply voltage accordingly.
• How do I handle the asynchronous reset input (SR) on the 74HC597D,652?
  The asynchronous reset input (SR) should be tied to VCC through a pull-up resistor to ensure that the device is not accidentally reset. A 1 kΩ to 10 kΩ pull-up resistor is recommended.
• What is the maximum capacitive load that can be driven by the 74HC597D,652?
  The maximum capacitive load that can be driven by the 74HC597D,652 is 50 pF, but this can be limited by the system's noise margin and the quality of the clock signal.
