The recommended operating voltage range for the 74ACT11030D is 4.5V to 5.5V, as specified in the datasheet. However, it's recommended to operate the device at a fixed voltage of 5V for optimal performance.
When the input pins are not in use, it's recommended to tie them to VCC or GND through a pull-up or pull-down resistor to prevent floating inputs and reduce power consumption.
The maximum frequency of operation for the 74ACT11030D is typically limited by the propagation delay and clock skew. According to the datasheet, the maximum clock frequency is around 100 MHz, but this can vary depending on the specific application and board design.
To ensure signal integrity and reduce noise, it's recommended to use proper PCB design techniques such as using a solid ground plane, minimizing trace lengths, and using decoupling capacitors. Additionally, consider using series termination resistors and/or parallel termination resistors to reduce signal reflections and ringing.
While the 74ACT11030D is specified for 5V operation, it can be used in a 3.3V system with some limitations. The device will still function, but the output voltage levels may not be as strong, and the noise margin may be reduced. It's recommended to consult the datasheet and perform thorough testing to ensure the device meets the system requirements.
