The recommended operating voltage range for the HEF40174BT,653 is 4.5V to 15.5V, with a typical operating voltage of 5V.
To ensure reliable operation of the flip-flops, make sure to meet the setup and hold time requirements, and avoid clock skew and jitter. Also, ensure that the input signals are clean and free of noise.
Yes, the HEF40174BT,653 can operate at 3.3V, but the output voltage levels may not be as high as at 5V. Check the datasheet for the output voltage levels at 3.3V.
The asynchronous reset input (MR) should be tied to VCC through a pull-up resistor or connected to a reset signal. Avoid leaving it floating, as this can cause unpredictable behavior.
The maximum clock frequency that the HEF40174BT,653 can handle is typically around 30MHz, but this can vary depending on the specific application and operating conditions. Check the datasheet for more information.
