CD74HC73E datasheet by Texas Instruments

CD74HC73E Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the CD74HC73E?
  The CD74HC73E can operate at frequencies up to 25 MHz.
• How do I ensure that the CD74HC73E is properly powered?
  The CD74HC73E requires a power supply voltage (VCC) of 2.0 V to 6.0 V, and it is recommended to decouple the power supply with a 0.1 μF capacitor.
• What is the propagation delay time for the CD74HC73E?
  The propagation delay time (tPD) for the CD74HC73E is typically around 10 ns, but it can vary depending on the operating conditions and load capacitance.
• Can I use the CD74HC73E in a 3.3 V system?
  Yes, the CD74HC73E can operate at 3.3 V, but the output voltage levels may not be compatible with 3.3 V systems. It is recommended to use a level translator or a voltage regulator to ensure compatibility.
• How do I handle the input and output pins during power-up and power-down?
  It is recommended to tie the input pins to a valid logic level during power-up and power-down to prevent unwanted switching. The output pins should be tied to a load or a pull-up/pull-down resistor to prevent floating.
