M74HC11B1R Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for M74HC11B1R?
  The recommended operating voltage range for M74HC11B1R is 2V to 6V, with a typical voltage of 5V.
• How do I handle the power-up and power-down sequences for M74HC11B1R?
  It's recommended to follow a slow power-up and power-down sequence to prevent latch-up and ensure proper operation. A ramp-up time of 10ms to 100ms and a ramp-down time of 10ms to 100ms is recommended.
• What is the maximum clock frequency supported by M74HC11B1R?
  The maximum clock frequency supported by M74HC11B1R is 16MHz, but it's recommended to operate at a frequency below 10MHz for reliable operation.
• How do I ensure electromagnetic compatibility (EMC) with M74HC11B1R?
  To ensure EMC, it's recommended to use a decoupling capacitor (e.g., 100nF) between VCC and GND, and to minimize the length of the clock signal trace. Additionally, use a shielded cable for the clock signal and keep it away from noisy signals.
• What is the maximum output current for each I/O pin of M74HC11B1R?
  The maximum output current for each I/O pin of M74HC11B1R is 25mA, but it's recommended to limit the output current to 10mA to ensure reliable operation.
