SN74AHC273DWR datasheet by Texas Instruments

SN74AHC273DWR Frequently Asked Questions (FAQs)

• What is the maximum clock frequency that the SN74AHC273DWR can handle?
  The maximum clock frequency of the SN74AHC273DWR is 100 MHz.
• How do I ensure that the outputs of the SN74AHC273DWR are not corrupted during power-up or power-down?
  To ensure that the outputs are not corrupted during power-up or power-down, it is recommended to use an external pull-up or pull-down resistor on the output pins, and to ensure that the power supply voltage (VCC) is stable before applying clock signals.
• Can I use the SN74AHC273DWR in a 5V system?
  Yes, the SN74AHC273DWR is compatible with 5V systems, but it is recommended to use a voltage regulator to ensure that the supply voltage (VCC) is within the recommended operating range of 4.5V to 5.5V.
• How do I handle the asynchronous reset (CLR) input?
  The asynchronous reset (CLR) input should be tied to VCC through a pull-up resistor (e.g., 1 kΩ) to ensure that the device is properly reset during power-up or when the CLR input is asserted.
• What is the maximum capacitance that can be driven by the SN74AHC273DWR?
  The maximum capacitance that can be driven by the SN74AHC273DWR is 100 pF.
