SN74HCT273DBR datasheet by Texas Instruments

SN74HCT273DBR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74HCT273DBR can handle?
  The maximum clock frequency of the SN74HCT273DBR is 30 MHz, but it can vary depending on the specific application and operating conditions.
• How do I ensure that the SN74HCT273DBR is properly powered?
  The SN74HCT273DBR requires a power supply voltage (VCC) of 4.5V to 5.5V, and it's recommended to use a decoupling capacitor of 0.1uF to 1uF between VCC and GND to reduce noise and ensure stable operation.
• What is the maximum current that the SN74HCT273DBR can sink or source?
  The SN74HCT273DBR can sink or source up to 6mA per output, but it's recommended to limit the current to 4mA per output to ensure reliable operation.
• How do I handle the asynchronous reset input (CLR) of the SN74HCT273DBR?
  The CLR input should be tied to VCC through a pull-up resistor (e.g., 1kΩ) to ensure that the flip-flops are properly reset. A low signal on CLR resets the flip-flops, and a high signal allows normal operation.
• What is the propagation delay of the SN74HCT273DBR?
  The propagation delay of the SN74HCT273DBR is typically around 10ns to 15ns, but it can vary depending on the specific application and operating conditions.
