SN74LS273NE4 Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74LS273NE4 is 35 MHz.
  • To ensure that the outputs are not corrupted during power-up or power-down, it is recommended to use a power-on reset (POR) circuit or a voltage supervisor to ensure that the device is fully powered up before the clock signal is applied.
  • Yes, the SN74LS273NE4 is compatible with 3.3V systems, but it is recommended to use a voltage regulator to ensure that the supply voltage is within the recommended operating range of 4.75V to 5.25V.
  • The asynchronous reset input (CLR) should be tied to VCC through a pull-up resistor to ensure that the device is not inadvertently reset. A 1kΩ to 10kΩ pull-up resistor is recommended.
  • The maximum capacitance that can be driven by the SN74LS273NE4 is 100 pF. Exceeding this limit may cause signal degradation or oscillation.
