SN74ALS873BDW datasheet by Texas Instruments

SN74ALS873BDW Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SN74ALS873BDW?
  The maximum operating frequency of the SN74ALS873BDW is 100 MHz, but it can vary depending on the specific application and operating conditions.
• How do I handle the power-up and power-down sequencing of the SN74ALS873BDW?
  It is recommended to power up the VCC pin before the input signals, and power down the VCC pin after the input signals. This ensures that the device is properly initialized and avoids any potential latch-up or damage.
• What is the recommended termination scheme for the SN74ALS873BDW?
  The recommended termination scheme for the SN74ALS873BDW is to use a 50-ohm resistor in series with the output pin, and a 50-ohm resistor to ground on the input pin. This helps to reduce reflections and improve signal integrity.
• Can I use the SN74ALS873BDW in a 3.3V system?
  Yes, the SN74ALS873BDW can be used in a 3.3V system, but it is recommended to use a voltage regulator to ensure that the supply voltage is within the recommended operating range of 4.5V to 5.5V.
• How do I handle the thermal management of the SN74ALS873BDW?
  The SN74ALS873BDW has a maximum junction temperature of 150°C. To ensure reliable operation, it is recommended to keep the device temperature below 125°C by using a heat sink or other thermal management techniques.
