SN54F74J datasheet by Texas Instruments

SN54F74J Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN54F74J can handle?
  The SN54F74J can handle clock frequencies up to 25 MHz.
• How do I ensure that the flip-flops are properly initialized on power-up?
  To ensure proper initialization, connect the preset (PRE) and clear (CLR) inputs to VCC through a 1-kΩ resistor and a 0.01-μF capacitor to ground, respectively.
• What is the recommended operating voltage range for the SN54F74J?
  The recommended operating voltage range for the SN54F74J is 4.5 V to 5.5 V.
• Can I use the SN54F74J in a 3.3-V system?
  No, the SN54F74J is not designed to operate at 3.3 V. It is recommended to use a voltage regulator or a level translator to ensure proper operation.
• How do I reduce power consumption in the SN54F74J?
  To reduce power consumption, use a lower clock frequency, minimize the number of transitions on the clock input, and consider using a low-power version of the device.
