The recommended operating voltage range for the SN74ACT1284DWR is 4.5V to 5.5V, with a typical voltage of 5V.
When the input pins are not in use, they should be tied to a valid logic level (either VCC or GND) to prevent them from floating and causing unwanted behavior.
The maximum frequency of operation for the SN74ACT1284DWR is 100 MHz, but this can vary depending on the specific application and operating conditions.
To ensure that the output signals are properly terminated, a pull-up or pull-down resistor should be used, and the output should be connected to a load that is within the recommended capacitive load range.
The power consumption of the SN74ACT1284DWR depends on the operating frequency and voltage, but typically it is around 20-30 mA at 5V and 50 MHz.
