SN74ALS273NSR Frequently Asked Questions (FAQ)

  • The maximum clock frequency of the SN74ALS273NSR is 100 MHz.

  • To ensure proper initialization, connect the CLR (clear) input to a power-on reset circuit or a manual reset switch. This ensures that the flip-flops are reset to a known state during power-up.

  • The recommended operating voltage range for the SN74ALS273NSR is 4.5V to 5.5V.

  • No, the SN74ALS273NSR is not designed to operate at 3.3V. It is recommended to use a voltage regulator or a level translator to ensure proper operation.

  • To handle asynchronous inputs, use synchronous inputs or add external synchronization circuits to ensure that the inputs are synchronized with the clock signal.
