SN74ALS273DWR Frequently Asked Questions (FAQs)

  • The maximum clock frequency of the SN74ALS273DWR is 100 MHz.
  • 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.
  • The recommended operating voltage range for the SN74ALS273DWR is 4.5V to 5.5V.
  • While the SN74ALS273DWR is specified for 5V operation, it can be used in a 3.3V system with some limitations. However, the output voltage levels may not be compatible with 3.3V logic, and the device's performance may be degraded.
  • To handle asynchronous inputs, use synchronous inputs whenever possible. If asynchronous inputs are unavoidable, use a synchronizer circuit to synchronize the inputs to the clock signal.
