The maximum frequency of operation for the SN74AC08N is typically around 100 MHz, but this can vary depending on the specific application and operating conditions.
To ensure proper operation, the SN74AC08N should be powered with a stable 5V supply, and decoupling capacitors (e.g. 0.1uF and 10uF) should be placed close to the device to filter out noise and reduce electromagnetic interference (EMI).
The SN74AC08N can sink or source up to 24mA of current per output, but this should be limited to 12mA per output to ensure reliable operation.
Unused inputs on the SN74AC08N should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper operation.
The SN74AC08N is a 5V device, but it can be used with 3.3V logic if the input and output levels are compatible. However, the device may not operate at its full speed and may require additional level-shifting circuitry.
