SN74HCT74PWR datasheet by Texas Instruments

SN74HCT74PWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HCT74PWR can handle?
  The maximum clock frequency of the SN74HCT74PWR is 30 MHz.
• How do I ensure that the flip-flops are properly initialized during power-up?
  To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to VCC or GND, and use a pull-up or pull-down resistor to prevent floating inputs.
• What is the recommended operating voltage range for the SN74HCT74PWR?
  The recommended operating voltage range for the SN74HCT74PWR is 4.5V to 5.5V.
• Can I use the SN74HCT74PWR in a 3.3V system?
  While the SN74HCT74PWR is specified for 5V operation, it can be used in a 3.3V system, but the output voltage levels may not meet the required specifications. It's recommended to use a voltage regulator or level translator to ensure compatibility.
• How do I reduce power consumption in my design using the SN74HCT74PWR?
  To reduce power consumption, use a lower clock frequency, minimize the number of flip-flops used, and consider using a low-power alternative, such as the 74AHC74 or 74LVC74.
