SN74HCT273NSR datasheet by Texas Instruments

SN74HCT273NSR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HCT273NSR can handle?
  The maximum clock frequency of the SN74HCT273NSR is 30 MHz, but it can vary depending on the system design and capacitive loading.
• How do I ensure that the flip-flops are properly initialized during power-up?
  To ensure proper initialization, connect the CLR (clear) input to a power-on reset circuit or a pull-up resistor to VCC. This ensures that the flip-flops are reset to a known state during power-up.
• What is the recommended operating voltage range for the SN74HCT273NSR?
  The recommended operating voltage range for the SN74HCT273NSR is 4.5V to 5.5V, with a typical voltage of 5V.
• How do I handle asynchronous inputs to the flip-flops?
  Asynchronous inputs should be synchronized to the clock signal using a synchronizer circuit or a flip-flop with a clock enable input to prevent metastability issues.
• What is the maximum capacitive load that the SN74HCT273NSR can drive?
  The maximum capacitive load that the SN74HCT273NSR can drive is 100 pF, but it's recommended to keep the load capacitance as low as possible to ensure reliable operation.
