MC74HC273ADTG Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the MC74HC273ADTG is 35 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure proper initialization, connect the CLR (clear) input to a power-on reset circuit or a manual reset switch. This will ensure that the flip-flops are reset to a known state during power-up.
  • The recommended operating voltage range for the MC74HC273ADTG is 2.0 V to 6.0 V, with a typical operating voltage of 5.0 V.
  • Asynchronous inputs should be synchronized with the clock signal using a synchronizer circuit or a flip-flop with a synchronous clear input to prevent metastability issues.
  • The maximum capacitance that can be driven by the MC74HC273ADTG outputs is 100 pF, but this can vary depending on the specific application and operating conditions.
