74AC11000DR datasheet by Texas Instruments

74AC11000DR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the 74AC11000DR?
  The recommended operating voltage range for the 74AC11000DR is 2.0V to 3.6V, with a typical voltage of 3.3V.
• How do I handle the output enable (OE) pin to ensure proper operation?
  The output enable (OE) pin should be connected to a logic low (GND) to enable the outputs, and to a logic high (VCC) to disable the outputs. Leaving the OE pin floating can cause unpredictable behavior.
• What is the maximum clock frequency supported by the 74AC11000DR?
  The maximum clock frequency supported by the 74AC11000DR is 100 MHz, but this can vary depending on the specific application and operating conditions.
• How do I ensure proper termination of the outputs to prevent signal reflections?
  To prevent signal reflections, it is recommended to use a series terminator (e.g., 22-33 ohms) at the far end of the transmission line, and to keep the trace length as short as possible.
• Can I use the 74AC11000DR in a 5V system?
  While the 74AC11000DR can tolerate 5V inputs, it is not recommended to operate the device at 5V, as it may exceed the maximum rating and reduce the device's lifespan. It's recommended to use a voltage regulator or level shifter to ensure a safe operating voltage.
