The SN74HC273DW can handle clock frequencies up to 35 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 SN74HC273DW is 2V to 6V, with a typical operating voltage of 5V.
Yes, the SN74HC273DW can be used in a 3.3V system, but ensure that the input signals are compatible with the device's input voltage levels.
To handle asynchronous inputs, use synchronous inputs or add external synchronization circuits to ensure that the inputs are synchronized with the clock signal.
