74HC126D,652 Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for the 74HC126D,652?
  The maximum frequency of operation for the 74HC126D,652 is typically around 100 MHz, but this can vary depending on the specific application, supply voltage, and output load.
• How do I ensure that the 74HC126D,652 is properly powered and decoupled?
  To ensure proper operation, the 74HC126D,652 should be powered from a stable, low-noise power supply, and decoupling capacitors (e.g., 100 nF) should be placed as close as possible to the device's power pins.
• What is the maximum output current that the 74HC126D,652 can sink or source?
  The 74HC126D,652 can sink or source up to 25 mA of output current per buffer, but this should be derated based on the ambient temperature and the number of buffers being used.
• Can I use the 74HC126D,652 as a level translator between different voltage domains?
  Yes, the 74HC126D,652 can be used as a level translator between different voltage domains, but the input and output voltage levels must be within the specified operating range, and the device's power supply voltage must be compatible with both voltage domains.
• How do I handle unused inputs on the 74HC126D,652?
  Unused inputs on the 74HC126D,652 should be tied to a valid logic level (either VCC or GND) to prevent floating inputs and ensure proper device operation.
