The maximum operating frequency of the SN74ALS09DR is typically around 100 MHz, but it can vary depending on the specific application and operating conditions.
The output current of the SN74ALS09DR is limited to 24 mA per output pin. If you need to drive a heavier load, you may need to use an external buffer or driver.
The input voltage threshold of the SN74ALS09DR is typically around 2.0 V for a logic high and 0.8 V for a logic low, but it can vary depending on the specific operating conditions.
Yes, the SN74ALS09DR can be used in a 3.3V system, but you may need to use external resistors to limit the output current and ensure that the output voltage is within the acceptable range for your system.
The SN74ALS09DR requires a single 5V power supply, but it can also be operated from a 4.5V to 5.5V power supply range. Make sure to decouple the power supply with a 0.1uF capacitor to reduce noise and ensure reliable operation.
