The SN74HC273PW 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 button. This will ensure that the flip-flops are reset to a known state on power-up.
The SN74HC273PW can drive up to 50 pF of capacitive load per output.
Yes, the SN74HC273PW is compatible with 5V systems. However, ensure that the input voltage (VCC) is within the recommended operating range of 2V to 6V.
To reduce power consumption, consider using a lower clock frequency, reducing the input signal transition times, and minimizing the number of outputs switching simultaneously.
