The maximum clock frequency of the 74HC273D is typically 25 MHz, but it can vary depending on the operating voltage and temperature. It's recommended to check the datasheet for specific frequency limits under different operating conditions.
To ensure proper power and decoupling, connect the VCC pin to a stable 2.0-6.0V power supply, and decouple the power supply lines with 0.1uF ceramic capacitors as close to the VCC pin as possible. Additionally, use a 10uF electrolytic capacitor to filter out any noise on the power supply lines.
The 74HC273D can sink or source up to 25mA of current per output pin, but it's recommended to limit the current to 10mA or less to ensure reliable operation and prevent overheating.
During power-up, the asynchronous reset input (MR) should be held low for at least 10ns to ensure that the flip-flops are properly reset. After power-up, the MR input can be released to allow normal operation.
Yes, the 74HC273D is compatible with 5V TTL logic levels, but it's recommended to use a voltage translator or level shifter if the system requires 3.3V or lower voltage levels.
