74AC11138D datasheet by Texas Instruments

74AC11138D Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for the 74AC11138D?
  The recommended operating voltage range for the 74AC11138D is 2.0V to 3.6V.
• How do I ensure signal integrity when using the 74AC11138D?
  To ensure signal integrity, use a low-impedance PCB design, minimize trace lengths, and use termination resistors as needed to reduce signal reflections.
• Can I use the 74AC11138D in a 5V system?
  While the 74AC11138D is specified for 2.0V to 3.6V operation, it can tolerate 5V inputs, but the output voltage will be limited to the supply voltage (VCC). However, it's not recommended to operate the device at 5V for extended periods.
• How do I handle power sequencing when using the 74AC11138D?
  To prevent latch-up, ensure that the power supply voltage (VCC) is applied before the input signals, and that the input signals are stable before the clock signal is applied.
• What is the maximum clock frequency supported by the 74AC11138D?
  The maximum clock frequency supported by the 74AC11138D is 100 MHz.
