M74HC390RM13TR Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for M74HC390RM13TR?
  The recommended operating voltage range for M74HC390RM13TR is 2V to 6V, with a typical voltage of 5V.
• How do I handle the power-up and power-down sequences for M74HC390RM13TR?
  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 proper initialization and prevents unwanted output states.
• What is the maximum clock frequency that M74HC390RM13TR can handle?
  The maximum clock frequency that M74HC390RM13TR can handle is 30 MHz, but this can vary depending on the operating voltage and load conditions.
• How do I ensure that the output signals of M74HC390RM13TR are not distorted or skewed?
  To ensure that the output signals are not distorted or skewed, it is recommended to use a low-impedance output driver, such as a 74HC series buffer, and to keep the output load capacitance below 50 pF.
• Can I use M74HC390RM13TR in a high-temperature environment?
  M74HC390RM13TR is rated for operation up to 125°C, but the device's performance and reliability may degrade at high temperatures. It is recommended to derate the device's operating frequency and voltage at high temperatures.
