SN74HC273DBR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74HC273DBR is 35 MHz, but it can vary depending on the specific application and operating conditions.
  • To ensure proper power and decoupling, use a 5V power supply, add a 0.1uF decoupling capacitor between VCC and GND, and use a 10uF bulk capacitor for each 10 devices on the board.
  • The SN74HC273DBR can sink or source up to 25mA per output, but it's recommended to limit the current to 10mA per output to ensure reliable operation.
  • The CLR input should be tied to VCC through a 1kΩ resistor and a 0.01uF capacitor to ensure proper reset operation. A pull-up resistor is not necessary.
  • While the SN74HC273DBR is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage will be lower, and the device may not meet the specified timing parameters.
